Compress::Zlib is vulnerable to a buffer overflow which could potentially lead to execution of arbitrary code.
|Package||perl-core/Compress-Zlib on all architectures|
|Affected versions||< 1.35|
|Unaffected versions||>= 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"
