CVE-2017-15129 4 Canonical, Fedoraproject, Linux and 1 more 20 Ubuntu Linux, Fedora, Linux Kernel and 17 more 2024-02-08 4.9 MEDIUM 4.7 MEDIUM
A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.
CVE-2023-4132 4 Debian, Fedoraproject, Linux and 1 more 6 Debian Linux, Fedora, Linux Kernel and 3 more 2024-02-07 N/A 5.5 MEDIUM
A use-after-free vulnerability was found in the siano smsusb module in the Linux kernel. The bug occurs during device initialization when the siano device is plugged in. This flaw allows a local user to crash the system, causing a denial of service condition.
CVE-2019-14865 2 Gnu, Redhat 3 Grub2, Enterprise Linux, Enterprise Linux Eus 2024-02-06 4.9 MEDIUM 5.5 MEDIUM
A flaw was found in the grub2-set-bootflag utility of grub2. A local attacker could run this utility under resource pressure (for example by setting RLIMIT), causing grub2 configuration files to be truncated and leaving the system unbootable on subsequent reboots.
CVE-2023-6679 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2024-02-06 N/A 5.5 MEDIUM
A null pointer dereference vulnerability was found in dpll_pin_parent_pin_set() in drivers/dpll/dpll_netlink.c in the Digital Phase Locked Loop (DPLL) subsystem in the Linux kernel. This issue could be exploited to trigger a denial of service.
CVE-2009-2416 11 Apple, Canonical, Debian and 8 more 19 Iphone Os, Mac Os X, Mac Os X Server and 16 more 2024-02-02 4.3 MEDIUM 6.5 MEDIUM
Multiple use-after-free vulnerabilities in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allow context-dependent attackers to cause a denial of service (application crash) via crafted (1) Notation or (2) Enumeration attribute types in an XML file, as demonstrated by the Codenomicon XML fuzzing framework.
CVE-2021-3714 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-02-01 N/A 5.9 MEDIUM
A flaw was found in the Linux kernels memory deduplication mechanism. Previous work has shown that memory deduplication can be attacked via a local exploitation mechanism. The same technique can be used if an attacker can upload page sized files and detect the change in access time from a networked service to determine if the page has been merged.
CVE-2023-2283 3 Fedoraproject, Libssh, Redhat 3 Fedora, Libssh, Enterprise Linux 2024-02-01 N/A 6.5 MEDIUM
A vulnerability was found in libssh, where the authentication check of the connecting client can be bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen if there is insufficient memory or the memory usage is limited. The problem is caused by the return value `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
CVE-2023-3772 4 Debian, Fedoraproject, Linux and 1 more 6 Debian Linux, Fedora, Linux Kernel and 3 more 2024-01-30 N/A 4.4 MEDIUM
A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel crash and denial of service.
CVE-2023-34968 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Enterprise Linux and 2 more 2024-01-30 N/A 5.3 MEDIUM
A path disclosure vulnerability was found in Samba. As part of the Spotlight protocol, Samba discloses the server-side absolute path of shares, files, and directories in the results for search queries. This flaw allows a malicious client or an attacker with a targeted RPC request to view the information that is part of the disclosed path.
CVE-2023-34967 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-01-30 N/A 5.3 MEDIUM
A Type Confusion vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets, one encoded data structure is a key-value style dictionary where the keys are character strings, and the values can be any of the supported types in the mdssvc protocol. Due to a lack of type checking in callers of the dalloc_value_for_key() function, which returns the object associated with a key, a caller may trigger a crash in talloc_get_size() when talloc detects that the passed-in pointer is not a valid talloc pointer. With an RPC worker process shared among multiple client connections, a malicious client or attacker can trigger a process crash in a shared RPC mdssvc worker process, affecting all other clients this worker serves.
CVE-2023-51764 3 Fedoraproject, Postfix, Redhat 3 Fedora, Postfix, Enterprise Linux 2024-01-30 N/A 5.3 MEDIUM
Postfix through 3.8.5 allows SMTP smuggling unless configured with smtpd_data_restrictions=reject_unauth_pipelining and smtpd_discard_ehlo_keywords=chunking (or certain other options that exist in recent versions). Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because Postfix supports <LF>.<CR><LF> but some other popular e-mail servers do not. To prevent attack variants (by always disallowing <LF> without <CR>), a different solution is required, such as the smtpd_forbid_bare_newline=yes option with a Postfix minimum version of 3.5.23, 3.6.13, 3.7.9, 3.8.4, or 3.9.
CVE-2024-0607 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2024-01-26 N/A 6.6 MEDIUM
A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality.
CVE-2021-4158 2 Qemu, Redhat 2 Qemu, Enterprise Linux 2024-01-25 N/A 6.0 MEDIUM
A NULL pointer dereference issue was found in the ACPI code of QEMU. A malicious, privileged user within the guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.
CVE-2023-4732 2 Linux, Redhat 10 Linux Kernel, Codeready Linux Builder, Codeready Linux Builder For Arm64 and 7 more 2024-01-25 N/A 4.7 MEDIUM
A flaw was found in pfn_swap_entry_to_page in memory management subsystem in the Linux Kernel. In this flaw, an attacker with a local user privilege may cause a denial of service problem due to a BUG statement referencing pmd_t x.
CVE-2023-4806 3 Fedoraproject, Gnu, Redhat 22 Fedora, Glibc, Codeready Linux Builder Eus and 19 more 2024-01-25 N/A 5.9 MEDIUM
A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags.
CVE-2023-5870 2 Postgresql, Redhat 16 Postgresql, Codeready Linux Builder Eus, Codeready Linux Builder Eus For Power Little Endian Eus and 13 more 2024-01-25 N/A 4.4 MEDIUM
A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.
CVE-2023-5868 2 Postgresql, Redhat 16 Postgresql, Codeready Linux Builder Eus, Codeready Linux Builder Eus For Power Little Endian Eus and 13 more 2024-01-25 N/A 4.3 MEDIUM
A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling 'unknown'-type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue exists due to excessive data output in aggregate function calls, enabling remote users to read some portion of system memory.
CVE-2023-46846 2 Redhat, Squid-cache 8 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 5 more 2024-01-22 N/A 5.3 MEDIUM
SQUID is vulnerable to HTTP request smuggling, caused by chunked decoder lenience, allows a remote attacker to perform Request/Response smuggling past firewall and frontend security systems.
CVE-2023-4813 4 Fedoraproject, Gnu, Netapp and 1 more 21 Fedora, Glibc, Active Iq Unified Manager and 18 more 2024-01-21 N/A 5.9 MEDIUM
A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.
CVE-2023-6277 3 Fedoraproject, Libtiff, Redhat 3 Fedora, Libtiff, Enterprise Linux 2024-01-19 N/A 6.5 MEDIUM
An out-of-memory flaw was found in libtiff. Passing a crafted tiff file to TIFFOpen() API may allow a remote attacker to cause a denial of service via a craft input with size smaller than 379 KB.
