OPENSUSE-SU-2026:20709-1
Vulnerability from csaf_opensuse - Published: 2026-05-09 08:44 - Updated: 2026-05-09 08:44Summary
Security update for tor
Severity
Critical
Notes
Title of the patch: Security update for tor
Description of the patch: This update for tor fixes the following issues:
Changes in tor:
- Update to 0.4.9.8
* Fix out-of-bounds read (boo#1264341, CVE-2026-44597, TROVE-2026-011)
* Do not attempt or accept BEGIN_DIR via conflux legs
(boo#1264342, CVE-2026-44599,TROVE-2026-008)
* Adjust conflux out-of-order queue accounting when clearing a queue
(boo#1264343, CVE-2026-44600, TROVE-2026-010)
* Fix a client-side crash caused by double-close of a circuit while
under circuit queue memory pressure
(boo#1264344, CVE-2026-44601, TROVE-2026-009)
* Fix null pointer dereference when receiving a CERT cell out of
order (boo#1264345, CVE-2026-44602, TROVE-2026-006)
* Fix off-by-one out-of-bounds read if a malformed BEGIN cell is
received (boo#1264346, CVE-2026-44603, TROVE-2026-007)
- upate to 0.4.9.5:
* first stable release in the 0.4.9 series
* introduces a new circuit-level encryption design for better
client security
* introduce a more scalable way for large relay operators to
annotate which relays they run so clients can avoid using too
many of them in a single circuit
