Package : libarchive
Date : December 18, 2011
Affected: Enterprise Server 5.0
_______________________________________________________________________
Problem Description:
A heap-based buffer overflow flaw was discovered in libarchive. If
a user were tricked into expanding a specially-crafted ISO 9660
CD-ROM image or tar archive with an application using libarchive,
it could cause the application to crash or, potentially, execute
arbitrary code with the privileges of the user running the application
(CVE-2011-1778).
The updated packages have been patched to correct these issues.
