All supported architectures
Compress::Zlib is vulnerable to a buffer overflow which could potentially
lead to execution of arbitrary code.
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
There is no known workaround at this time.
All Compress::Zlib users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=perl-core/Compress-Zlib-1.35"
