GLSA-200507-28 : AMD64 x86 emulation base libraries: Buffer overflow

high Nessus Plugin ID 19330

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200507-28 (AMD64 x86 emulation base libraries: Buffer overflow)

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.

Solution

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
