CVE-2021-30581 2 Fedoraproject, Google 2 Fedora, Chrome 2023-12-10 6.8 MEDIUM 8.8 HIGH
Use after free in DevTools in Google Chrome prior to 92.0.4515.107 allowed an attacker who convinced a user to install a malicious extension to potentially exploit heap corruption via a crafted HTML page.
CVE-2021-32917 3 Debian, Fedoraproject, Prosody 3 Debian Linux, Fedora, Prosody 2023-12-10 4.3 MEDIUM 5.3 MEDIUM
An issue was discovered in Prosody before 0.11.9. The proxy65 component allows open access by default, even if neither of the users has an XMPP account on the local server, allowing unrestricted use of the server's bandwidth.
CVE-2021-28698 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2023-12-10 4.9 MEDIUM 5.5 MEDIUM
long running loops in grant table handling In order to properly monitor resource use, Xen maintains information on the grant mappings a domain may create to map grants offered by other domains. In the process of carrying out certain actions, Xen would iterate over all such entries, including ones which aren't in use anymore and some which may have been created but never used. If the number of entries for a given domain is large enough, this iterating of the entire table may tie up a CPU for too long, starving other domains or causing issues in the hypervisor itself. Note that a domain may map its own grants, i.e. there is no need for multiple domains to be involved here. A pair of "cooperating" guests may, however, cause the effects to be more severe.
CVE-2021-39146 5 Debian, Fedoraproject, Netapp and 2 more 15 Debian Linux, Fedora, Snapmanager and 12 more 2023-12-10 6.0 MEDIUM 8.5 HIGH
XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to load and execute arbitrary code from a remote host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.
CVE-2021-29648 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2023-12-10 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in the Linux kernel before 5.11.11. The BPF subsystem does not properly consider that resolved_ids and resolved_sizes are intentionally uninitialized in the vmlinux BPF Type Format (BTF), which can cause a system crash upon an unexpected access attempt (in map_create in kernel/bpf/syscall.c or check_btf_info in kernel/bpf/verifier.c), aka CID-350a5c4dd245.
CVE-2021-28163 5 Apache, Eclipse, Fedoraproject and 2 more 23 Ignite, Solr, Jetty and 20 more 2023-12-10 4.0 MEDIUM 2.7 LOW
In Eclipse Jetty 9.4.32 to 9.4.38, 10.0.0.beta2 to 10.0.1, and 11.0.0.beta2 to 11.0.1, if a user uses a webapps directory that is a symlink, the contents of the webapps directory is deployed as a static webapp, inadvertently serving the webapps themselves and anything else that might be in that directory.
CVE-2020-28200 2 Dovecot, Fedoraproject 2 Dovecot, Fedora 2023-12-10 4.0 MEDIUM 4.3 MEDIUM
The Sieve engine in Dovecot before 2.3.15 allows Uncontrolled Resource Consumption, as demonstrated by a situation with a complex regular expression for the regex extension.
CVE-2021-24119 3 Arm, Debian, Fedoraproject 3 Mbed Tls, Debian Linux, Fedora 2023-12-10 4.0 MEDIUM 4.9 MEDIUM
In Trusted Firmware Mbed TLS 2.24.0, a side-channel vulnerability in base64 PEM file decoding allows system-level (administrator) attackers to obtain information about secret RSA keys via a controlled-channel and side-channel attack on software running in isolated environments that can be single stepped, especially Intel SGX.
CVE-2021-32678 2 Fedoraproject, Nextcloud 2 Fedora, Nextcloud Server 2023-12-10 5.0 MEDIUM 5.3 MEDIUM
Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.0.11, and 21.0.3, ratelimits are not applied to OCS API responses. This affects any OCS API controller (`OCSController`) using the `@BruteForceProtection` annotation. Risk depends on the installed applications on the Nextcloud Server, but could range from bypassing authentication ratelimits or spamming other Nextcloud users. The vulnerability is patched in versions 19.0.13, 20.0.11, and 21.0.3. No workarounds aside from upgrading are known to exist.
CVE-2021-20291 3 Fedoraproject, Redhat, Storage Project 4 Fedora, Enterprise Linux, Openshift Container Platform and 1 more 2023-12-10 7.1 HIGH 6.5 MEDIUM
A deadlock vulnerability was found in 'github.com/containers/storage' in versions before 1.28.1. When a container image is processed, each layer is unpacked using `tar`. If one of those layers is not a valid `tar` archive this causes an error leading to an unexpected situation where the code indefinitely waits for the tar unpacked stream, which never finishes. An attacker could use this vulnerability to craft a malicious image, which when downloaded and stored by an application using containers/storage, would then cause a deadlock leading to a Denial of Service (DoS).
CVE-2021-39252 3 Debian, Fedoraproject, Tuxera 3 Debian Linux, Fedora, Ntfs-3g 2023-12-10 6.9 MEDIUM 7.8 HIGH
A crafted NTFS image can cause an out-of-bounds read in ntfs_ie_lookup in NTFS-3G < 2021.8.22.
CVE-2021-32625 2 Fedoraproject, Redislabs 2 Fedora, Redis 2023-12-10 6.5 MEDIUM 8.8 HIGH
Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. An integer overflow bug in Redis version 6.0 or newer, could be exploited using the STRALGO LCS command to corrupt the heap and potentially result with remote code execution. This is a result of an incomplete fix by CVE-2021-29477. The problem is fixed in version 6.2.4 and 6.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to use ACL configuration to prevent clients from using the STRALGO LCS command. On 64 bit systems which have the fixes of CVE-2021-29477 (6.2.3 or 6.0.13), it is sufficient to make sure that the proto-max-bulk-len config parameter is smaller than 2GB (default is 512MB).
CVE-2021-0089 3 Debian, Fedoraproject, Intel 12 Debian Linux, Fedora, Celeron Processors and 9 more 2023-12-10 2.1 LOW 6.5 MEDIUM
Observable response discrepancy in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.
CVE-2021-35268 3 Debian, Fedoraproject, Tuxera 3 Debian Linux, Fedora, Ntfs-3g 2023-12-10 6.9 MEDIUM 7.8 HIGH
In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode is loaded in the function ntfs_inode_real_open, a heap buffer overflow can occur allowing for code execution and escalation of privileges.
CVE-2021-25217 5 Debian, Fedoraproject, Isc and 2 more 26 Debian Linux, Fedora, Dhcp and 23 more 2023-12-10 3.3 LOW 7.4 HIGH
In ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16, ISC DHCP 4.4.0 -> 4.4.2 (Other branches of ISC DHCP (i.e., releases in the 4.0.x series or lower and releases in the 4.3.x series) are beyond their End-of-Life (EOL) and no longer supported by ISC. From inspection it is clear that the defect is also present in releases from those series, but they have not been officially tested for the vulnerability), The outcome of encountering the defect while reading a lease that will trigger it varies, according to: the component being affected (i.e., dhclient or dhcpd) whether the package was built as a 32-bit or 64-bit binary whether the compiler flag -fstack-protection-strong was used when compiling In dhclient, ISC has not successfully reproduced the error on a 64-bit system. However, on a 32-bit system it is possible to cause dhclient to crash when reading an improper lease, which could cause network connectivity problems for an affected system due to the absence of a running DHCP client process. In dhcpd, when run in DHCPv4 or DHCPv6 mode: if the dhcpd server binary was built for a 32-bit architecture AND the -fstack-protection-strong flag was specified to the compiler, dhcpd may exit while parsing a lease file containing an objectionable lease, resulting in lack of service to clients. Additionally, the offending lease and the lease immediately following it in the lease database may be improperly deleted. if the dhcpd server binary was built for a 64-bit architecture OR if the -fstack-protection-strong compiler flag was NOT specified, the crash will not occur, but it is possible for the offending lease and the lease which immediately followed it to be improperly deleted.
CVE-2021-3573 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2023-12-10 6.9 MEDIUM 6.4 MEDIUM
A use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(), hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5.
CVE-2021-34555 2 Fedoraproject, Trusteddomain 2 Fedora, Opendmarc 2023-12-10 5.0 MEDIUM 7.5 HIGH
OpenDMARC 1.4.1 and 1.4.1.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a multi-value From header field.
CVE-2021-35477 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2023-12-10 2.1 LOW 5.5 MEDIUM
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value.
CVE-2021-21217 3 Debian, Fedoraproject, Google 3 Debian Linux, Fedora, Chrome 2023-12-10 4.3 MEDIUM 5.5 MEDIUM
Uninitialized data in PDFium in Google Chrome prior to 90.0.4430.72 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted PDF file.
CVE-2021-23134 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2023-12-10 4.6 MEDIUM 7.8 HIGH
Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability.
