Description Vladimir Vasilev 2026-08-22 11:48:07 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

tor before 0.4.9.9 was prone to an out-of-bounds write when parsing a consensus or  detached signature with unexpected signature digest type. Impact  is minor for most Tor roles, but potentially major for directory   authorities. This is TROVE-2026-019.
