+ <title>AMD64 x86 emulation base libraries: Buffer overflow</title>
+ <synopsis>
+ The x86 emulation base libraries for AMD64 contain a vulnerable version of
+ zlib which could potentially lead to execution of arbitrary code.
+ </synopsis>
+ <product type="ebuild">emul-linux-x86-baselibs</product>

+ <affected>
+ <package name="app-emulation/emul-linux-x86-baselibs" auto="yes" arch="AMD64">

+ <vulnerable range="lt">2.1.2</vulnerable>

+ <background>
+ <p>
+ The x86 emulation base libraries for AMD64 emulate the x86 (32-bit)
+ architecture on the AMD64 (64-bit) architecture.
+ </p>
+ </background>
+ <description>
+ <p>
+ Earlier versions of emul-linux-x86-baselibs contain a 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 the x86 emulation
+ base libraries for AMD64, 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 AMD64 x86 emulation base libraries users should upgrade to the
+ latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose app-emulation/emul-linux-x86-baselibs</code>
+ </resolution>
