USN-8283-1 rsync vulnerabilities
Calum Hutton discovered that rsync contained a heap-based out-of-bounds read when handling file transfers. A remote attacker with read access to an rsync server could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 25.1...
CVE-2026-44933
PluginScript attempts to chroot the plugin to the repoManagerRoot, this root is frequently / the system root in standard configurations or when using --root. If the chroot target is /, it is a no-op, allowing the traversed path to execute host binaries like /bin/bash with root privileges...
CVE-2026-41054
In src/havegecmd.c, the sockethandler function performs a credential check on the abstract UNIX socket \0/sys/entropy/haveged. However, while it detects if the connecting user is not root cred.uid != 0 and prepares a negative acknowledgement ASCIINAK, it fails to stop execution. The code proceeds...

CVE-2026-41054
CVE-2026-41054 affects haveged. In haveged’s source havegecmd.c, socket_handler checks the caller via an abstract UNIX socket and returns a negative acknowledgment for non-root users, but execution is not halted, enabling a local unprivileged user to reach privileged actions (e.g., MAGIC_CHROOT)....

CVE-2026-44933 Path Traversal in Plugin Loading in libzypp
PluginScript attempts to chroot the plugin to the repoManagerRoot, this root is frequently / the system root in standard configurations or when using --root. If the chroot target is /, it is a no-op, allowing the traversed path to execute host binaries like /bin/bash with root privileges...
CVE-2026-44933
CVE-2026-44933 affects the libzypp component’s PluginScript during plugin loading. The vulnerability arises when a plugin is chrooted to repoManagerRoot; if the target is “/” (which is common in standard configurations or when using --root), the chroot becomes a no-op, but the traversed path can ...
Time-of-check Time-of-use (TOCTOU) Race Condition
Overview Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition via the timing window between path resolution and syscall execution in operations such as chmod, lchown, utimes, rename, unlink, mkdir, symlink, mknod, link, rmdir, and lstat. An attacker...
Authentication Bypass by Alternate Name
Overview Affected versions of this package are vulnerable to Authentication Bypass by Alternate Name via the hostname-based access control list enforcement process when configured with chroot. An attacker can gain unauthorized access by manipulating the PTR record for their source IP address,...
DEBIAN-CVE-2026-43617
Rsync version 3.4.2 and prior contain an authorization bypass vulnerability in the rsync daemon's hostname-based access control list enforcement when configured with chroot. Attackers can bypass hostname-based deny rules by controlling the PTR record for their source IP address, allowing...
DEBIAN-CVE-2026-43619
Rsync version 3.4.2 and prior contain symlink race condition vulnerabilities in path-based system calls including chmod, lchown, utimes, rename, unlink, mkdir, symlink, mknod, link, rmdir, and lstat that allow local attackers to redirect operations to files outside the exported rsync module...
