|Gentoo Linux Security Advisory
Title: AMD64 x86 emulation base libraries: Buffer overflow (GLSA 200507-28)
Date: July 30, 2005
Updated: August 02, 2005
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.
Vulnerable: < 2.1.2
Unaffected: >= 2.1.2
Earlier versions of emul-linux-x86-baselibs contain a 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 the x86 emulation base libraries for AMD64, resulting in a Denial of Service and potentially arbitrary code execution.
There is no known workaround at this time.
All AMD64 x86 emulation base libraries users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose app-emulation/emul-linux-x86-baselibs
