Description

The 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.

Impact :

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.

Workaround :

There is no known workaround at this time.
