Compress::Zlib: Buffer overflow

Compress::Zlib: Buffer overflow Compress::Zlib is vulnerable to a buffer overflow which could potentially lead to execution of arbitrary code. Compress-Zlib 2005-08-01 2009-05-28 100540 remote 1.35 1.35

The Compress::Zlib is a Perl module which provides an interface to the zlib compression library.

Compress::Zlib 1.34 contains a local vulnerable version of zlib, which may lead to a buffer overflow.

By creating a specially crafted compressed data stream, attackers can overwrite data structures for applications that use Compress::Zlib, resulting in a Denial of Service and potentially arbitrary code execution.

There is no known workaround at this time.

All Compress::Zlib users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=perl-core/Compress-Zlib-1.35"
