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
