+ <title>Compress::Zlib: Buffer overflow</title>
+ <synopsis>
+ Compress::Zlib is vulnerable to a buffer overflow which could potentially
+ lead to execution of arbitrary code.

+ <affected>
+ <package name="perl-core/Compress-Zlib" auto="yes" arch="*">

+ <background>
+ <p>
+ The Compress::Zlib is a Perl module which provides an interface to
+ the zlib compression library.
+ </p>
+ </background>
+ <description>
+ <p>
+ Compress::Zlib 1.34 contains a local vulnerable version of zlib,
+ which may lead to a buffer overflow.
+ </p>
+ </description>
+ <impact type="high">
+ <p>
+ 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.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Compress::Zlib users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=perl-core/Compress-Zlib-1.35"</code>
+ </resolution>
