CVE-2012-3518

Publication date 26 August 2012

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The networkstatus_parse_vote_from_string function in routerparse.c in Tor before 0.2.2.38 does not properly handle an invalid flavor name, which allows remote attackers to cause a denial of service (out-of-bounds read and daemon crash) via a crafted (1) vote document or (2) consensus document.
