Ubuntu Security Notice 5918-1 - It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code. Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.
Ubuntu Security Notice 5917-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service or execute arbitrary code.
Ubuntu Security Notice 5919-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability.

debmany in debian-goodies 0.88.1 allows attackers to execute arbitrary shell commands (because of an eval call) via a crafted .deb file. (The path is shown to the user before execution.)
Ghost 5.35.0 allows authorization bypass: contributors can view draft posts of other users, which is arguably inconsistent with a security policy in which a contributor's draft can only be read by editors until published by an editor. NOTE: the vendor's position is that this behavior has no security impact.
mailcow is a dockerized email package, with multiple containers linked in one bridged network. The Sync Job feature - which can be made available to standard users by assigning them the necessary permission - suffers from a shell command injection. A malicious user can abuse this vulnerability to obtain shell access to the Docker container running dovecot. The imapsync Perl script implements all the necessary functionality for this feature, including the XOAUTH2 authentication mechanism. This code path creates a shell command to call openssl. However, since different parts of the specified user password are included without any validation, one can simply execute additional shell commands. Notably, the default ACL for a newly-created mailcow account does not include the necessary permission. The Issue has been fixed within the 2023-03 Update (March 3rd 2023). As a temporary workaround the Syncjob ACL can be removed from all mailbox users, preventing from creating or changing existing Sy...
RSSHub is an open source and extensible RSS feed generator. When the URL parameters contain certain special characters, it returns an error page that does not properly handle XSS vulnerabilities, allowing for the execution of arbitrary JavaScript code. Users who access the deliberately constructed URL are affected. This vulnerability was fixed in version c910c4d28717fb860fbe064736641f379fab2c91. Please upgrade to this or a later version, there are no known workarounds.
