Description

The remote host is affected by the vulnerability described in GLSA-200908-07 (Perl Compress::Raw modules: Denial of Service)

Leo Bergolth reported an off-by-one error in the inflate() function in     Zlib.xs of Compress::Raw::Zlib, possibly leading to a heap-based buffer     overflow (CVE-2009-1391).
Paul Marquess discovered a similar vulnerability in the bzinflate()     function in Bzip2.xs of Compress::Raw::Bzip2 (CVE-2009-1884).

Impact :

A remote attacker might entice a user or automated system (for instance     running SpamAssassin or AMaViS) to process specially crafted files,     possibly resulting in a Denial of Service condition.

Workaround :

There is no known workaround at this time.
