Severity: High Title: AMD64 x86 emulation base libraries: Buffer overflow Date: July 30, 2005 Bugs: #100686 ID: 200507-28
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis ========
The x86 emulation base libraries for AMD64 contain a vulnerable version of zlib which could potentially lead to execution of arbitrary code.
Background ==========
The x86 emulation base libraries for AMD64 emulate the x86 (32-bit) architecture on the AMD64 (64-bit) architecture.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 emul-linux-x86-baselibs < 2.2 >= 2.2 ------------------------------------------------------------------- # Package 1 only applies to AMD64 users.
Description ===========
Earlier versions of emul-linux-x86-baselibs contain a vulnerable version of zlib, which may lead to a buffer overflow.
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
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-2.2"
