+ <title>zlib: Buffer overflow</title>
+ <synopsis>
+ zlib is vulnerable to a buffer overflow which could potentially lead to
+ execution of arbitrary code.
+ </synopsis>
+ <product type="ebuild">zlib</product>
+ <announced>July 22, 2005</announced>
+ <revised>July 22, 2005: 01</revised>
+ <bug>99751</bug>
+ <access>remote</access>
+ <affected>
+ <package name="sys-libs/zlib" auto="yes" arch="*">
+ <unaffected range="ge">1.2.3</unaffected>
+ <vulnerable range="lt">1.2.3</vulnerable>
+ </package>

+ <background>
+ <p>
+ zlib is a widely used free and patent unencumbered data
+ compression library.
+ </p>
+ </background>
+ <description>
+ <p>
+ zlib improperly handles invalid data streams which could 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 zlib, resulting
+ in arbitrary code execution or a Denial of Service.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All zlib users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=sys-libs/zlib-1.2.3&quot;</code>
+ </resolution>
