acl: Symlink traversal privilege escalation via libacl functions

A flaw was found in the acl package, specifically within its libacl pathname-based functions. A local attacker could exploit this vulnerability by using a symbolic link to replace a pathname component. This could allow the attacker to redirect access control list ACL read or write operations to...

CVE-2026-8933

A local privilege escalation vulnerability exists in snap-confine, a set-capabilities core component used internally by Canonical snapd to construct the secure execution environment for snap applications. This vulnerability uniquely affects versions of snap-confine configured with set-capabilitie...

USN-8579-1: snapd vulnerabilities

James Henstridge discovered that snapd's default apparmor template did not restrict access to systemd-userdbd varlink interface. A local attacker could possibly use this issue to obtain sensitive information. CVE-2024-5300 Qualys discovered that snap-confine can be tricked to create...

CVE-2026-59851 Libssh: libssh: authentication bypass via missing gssapi principal check

A flaw was found in libssh. On servers with GSSAPIKeyExchange enabled, the gssapi-keyex path does not verify whether the authenticated Kerberos principal is authorized for the requested local user, allowing authenticated clients to log in as arbitrary users...

Incorrect Authorization

Overview Affected versions of this package are vulnerable to Incorrect Authorization in the gssapi-keyex process due to missing verification of the Kerberos principal's authorization for the requested local user. An attacker can gain unauthorized access as arbitrary users by exploiting this flaw...
