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).
|
|
</p>
|
|
<p>
|
|
Paul Marquess discovered a similar vulnerability in the bzinflate()
|
|
function in Bzip2.xs of Compress::Raw::Bzip2 (CVE-2009-1884).

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.
