GLSA-200804-02 : bzip2: Denial of Service
Medium Nessus Plugin ID 31753
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200804-02 (bzip2: Denial of Service)
The Oulu University discovered that bzip2 does not properly check offsets provided by the bzip2 file, leading to a buffer overread.
Remote attackers can entice a user or automated system to open a specially crafted file that triggers a buffer overread, causing a Denial of Service. libbz2 and programs linking against it are also affected.
There is no known workaround at this time.
SolutionAll bzip2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/bzip2-1.0.5'
