<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.

The x86 emulation base libraries for AMD64 emulate the x86 (32-bit)
|
|
architecture on the AMD64 (64-bit) architecture.

|

Earlier versions of emul-linux-x86-baselibs contain a vulnerable
|
|
version of zlib, which may lead to a buffer overflow.

<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>
