GLSA-200712-13 : E2fsprogs: Multiple buffer overflows
Medium Nessus Plugin ID 29733
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200712-13 (E2fsprogs: Multiple buffer overflows)
Rafal Wojtczuk (McAfee AVERT Research) discovered multiple integer overflows in libext2fs, that are triggered when processing information from within the file system, resulting in heap-based buffer overflows.
An attacker could entice a user to process a specially crafted ext2 or ext3 file system image (with tools linking against libext2fs, e.g.
fsck, forensic tools or Xen's pygrub), possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
SolutionAll E2fsprogs users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-fs/e2fsprogs-1.40.3'
