USN-8349-1 fixed vulnerabilities in rsync. The update introduced multiple
regressions in rsync functionality. This update fixes the problem.
Original advisory details:
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. (CVE-2025-10158)
Batuhan Sancak, Damien Neil, and Michael Stapelberg discovered that
rsync daemons configured without chroot protection were exposed to a
race condition on parent path components. A local attacker with write
access to a module could possibly use this issue to overwrite files,
obtain sensitive information, or escalate privileges.
(CVE-2026-29518)

condition in path-based system calls for daemons configured without
chroot protection. A local attacker could possibly use this issue to
overwrite files, obtain sensitive information, or escalate privileges.
(CVE-2026-43619)

possibly use this issue to overwrite lp-writable files and cause a denial
of service. (CVE-2026-34978)
Jacob Newman discovered that CUPS incorrectly handled filter option strings
when processing job attributes. An attacker could use this issue to cause
CUPS to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2026-34979)
Asim Viladi Oglu Manizada discovered that CUPS incorrectly handled
page-border values in shared PostScript queues. A remote attacker could
possibly use this issue to execute arbitrary code. (CVE-2026-34980)
Asim Viladi Oglu Manizada discovered that CUPS incorrectly handled
localhost authentication to attacker-controlled IPP services. A local
attacker could possibly use this issue to overwrite arbitrary files
and execute arbitrary code. (CVE-2026-34990)
Tomer Fichman discovered that CUPS incorrectly handled negative
job-password-supported values. A local attacker could possibly use this
issue to cause CUPS to crash, resulting in a denial of service.
(CVE-2026-39314)
Tomer Fichman discovered that CUPS incorrectly handled temporary printer
deletion. An attacker could possibly use this issue to cause CUPS to crash,
resulting in a denial of service, or to execute arbitrary code.
(CVE-2026-39316)
Tomer Fichman discovered that CUPS incorrectly handled certain malformed
SNMP responses. An attacker could possibly use this issue to obtain
sensitive information. (CVE-2026-41079)
