Vulnerability Assessment Details

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

Vulnerability Assessment Summary
AMD64 x86 emulation base libraries: Buffer overflow

Detailed Explanation for this Vulnerability Assessment
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.
