CVE-2021-3905 4 Canonical, Fedoraproject, Openvswitch and 1 more 4 Ubuntu Linux, Fedora, Openvswitch and 1 more 2023-12-10 N/A 7.5 HIGH
A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments.
CVE-2022-44544 2 Canonical, Mahara 2 Ubuntu Linux, Mahara 2023-12-10 N/A 9.8 CRITICAL
Mahara 21.04 before 21.04.7, 21.10 before 21.10.5, 22.04 before 22.04.3, and 22.10 before 22.10.0 potentially allow a PDF export to trigger a remote shell if the site is running on Ubuntu and the flag -dSAFER is not set with Ghostscript.
CVE-2022-40277 3 Canonical, Joplinapp, Linux 3 Ubuntu Linux, Joplin, Linux Kernel 2023-12-10 N/A 7.8 HIGH
Joplin version 2.8.8 allows an external attacker to execute arbitrary commands remotely on any client that opens a link in a malicious markdown file, via Joplin. This is possible because the application does not properly validate the schema/protocol of existing links in the markdown file before passing them to the 'shell.openExternal' function.
CVE-2022-34918 4 Canonical, Debian, Linux and 1 more 13 Ubuntu Linux, Debian Linux, Linux Kernel and 10 more 2023-12-10 7.2 HIGH 7.8 HIGH
An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c.
CVE-2022-39177 3 Bluez, Canonical, Debian 3 Bluez, Ubuntu Linux, Debian Linux 2023-12-10 N/A 8.8 HIGH
BlueZ before 5.59 allows physically proximate attackers to cause a denial of service because malformed and invalid capabilities can be processed in profiles/audio/avdtp.c.
CVE-2022-39176 3 Bluez, Canonical, Debian 3 Bluez, Ubuntu Linux, Debian Linux 2023-12-10 N/A 8.8 HIGH
BlueZ before 5.59 allows physically proximate attackers to obtain sensitive information because profiles/audio/avrcp.c does not validate params_len.
CVE-2022-40617 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-12-10 N/A 7.5 HIGH
strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing after the initial TCP handshake, or sends an excessive amount of application data.
CVE-2022-23238 5 Canonical, Centos, Linux and 2 more 5 Ubuntu Linux, Centos, Linux Kernel and 2 more 2023-12-10 N/A 6.5 MEDIUM
Linux deployments of StorageGRID (formerly StorageGRID Webscale) versions 11.6.0 through 11.6.0.2 deployed with a Linux kernel version less than 4.7.0 are susceptible to a vulnerability which could allow a remote unauthenticated attacker to view limited metrics information and modify alert email recipients and content.
CVE-2022-41222 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2023-12-10 N/A 7.0 HIGH
mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale TLB because an rmap lock is not held during a PUD move.
CVE-2021-3155 1 Canonical 2 Snapd, Ubuntu Linux 2023-12-10 2.1 LOW 5.5 MEDIUM
snapd 2.54.2 and earlier created ~/snap directories in user home directories without specifying owner-only permissions. This could allow a local attacker to read information that should have been private. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1
CVE-2021-4120 2 Canonical, Fedoraproject 3 Snapd, Ubuntu Linux, Fedora 2023-12-10 4.6 MEDIUM 7.8 HIGH
snapd 2.54.2 fails to perform sufficient validation of snap content interface and layout paths, resulting in the ability for snaps to inject arbitrary AppArmor policy rules via malformed content interface and layout declarations and hence escape strict snap confinement. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1
CVE-2020-25717 5 Canonical, Debian, Fedoraproject and 2 more 25 Ubuntu Linux, Debian Linux, Fedora and 22 more 2023-12-10 8.5 HIGH 8.1 HIGH
A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.
CVE-2022-0492 6 Canonical, Debian, Fedoraproject and 3 more 30 Ubuntu Linux, Debian Linux, Fedora and 27 more 2023-12-10 6.9 MEDIUM 7.8 HIGH
A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
CVE-2022-24760 3 Canonical, Microsoft, Parseplatform 3 Ubuntu Linux, Windows, Parse-server 2023-12-10 7.5 HIGH 10.0 CRITICAL
Parse Server is an open source http web server backend. In versions prior to 4.10.7 there is a Remote Code Execution (RCE) vulnerability in Parse Server. This vulnerability affects Parse Server in the default configuration with MongoDB. The main weakness that leads to RCE is the Prototype Pollution vulnerable code in the file `DatabaseController.js`, so it is likely to affect Postgres and any other database backend as well. This vulnerability has been confirmed on Linux (Ubuntu) and Windows. Users are advised to upgrade as soon as possible. The only known workaround is to manually patch your installation with code referenced at the source GHSA-p6h4-93qp-jhcm.
CVE-2021-44731 3 Canonical, Debian, Fedoraproject 4 Snapd, Ubuntu Linux, Debian Linux and 1 more 2023-12-10 6.9 MEDIUM 7.8 HIGH
A race condition existed in the snapd 2.54.2 snap-confine binary when preparing a private mount namespace for a snap. This could allow a local attacker to gain root privileges by bind-mounting their own contents inside the snap's private mount namespace and causing snap-confine to execute arbitrary code and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1
CVE-2022-29581 4 Canonical, Debian, Linux and 1 more 19 Ubuntu Linux, Debian Linux, Linux Kernel and 16 more 2023-12-10 7.2 HIGH 7.8 HIGH
Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions.
CVE-2021-3560 4 Canonical, Debian, Polkit Project and 1 more 7 Ubuntu Linux, Debian Linux, Polkit and 4 more 2023-12-10 7.2 HIGH 7.8 HIGH
It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25719 5 Canonical, Debian, Fedoraproject and 2 more 17 Ubuntu Linux, Debian Linux, Fedora and 14 more 2023-12-10 9.0 HIGH 7.2 HIGH
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise.
CVE-2016-2124 5 Canonical, Debian, Fedoraproject and 2 more 24 Ubuntu Linux, Debian Linux, Fedora and 21 more 2023-12-10 4.3 MEDIUM 5.9 MEDIUM
A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
CVE-2021-4115 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-12-10 2.1 LOW 5.5 MEDIUM
There is a flaw in polkit which can allow an unprivileged user to cause polkit to crash, due to process file descriptor exhaustion. The highest threat from this vulnerability is to availability. NOTE: Polkit process outage duration is tied to the failing process being reaped and a new one being spawned
