Debian DSA-2413-1 : libarchive - buffer overflows

Medium Nessus Plugin ID 58043


The remote Debian host is missing a security-related update.


Two buffer overflows have been discovered in libarchive, a library providing a flexible interface for reading and writing archives in various formats. The possible buffer overflows while reading ISO 9660 or tar streams allow remote attackers to execute arbitrary code depending on the application that makes use of this functionality.


Upgrade the libarchive packages.

For the stable distribution (squeeze), this problem has been fixed in version 2.8.4-1+squeeze1.
