Package : libarchive
Date : December 18, 2011
Affected: 2010.1, 2011.
_______________________________________________________________________
Problem Description:
Two heap-based buffer overflow flaws were 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-2011-1777, CVE-2011-1778).
The updated packages have been patched to correct these issues.
