CVE-2015-0860

Updated dpkg packages fix security vulnerability:

Hanno Boeck discovered a stack-based buffer overflow in the dpkg-deb component of dpkg. This flaw could potentially lead to arbitrary code execution if a user or an automated system were tricked into processing a specially crafted Debian binary package (.deb) in the old style Debian binary package format (CVE-2015-0860).

This update for dpkg fixes the following issues:

This security issue was fixed:

• CVE-2015-0860: Off-by-one error in the extracthalf function in dpkg-deb/extract.c in the dpkg-deb component in dpkg allowed remote attackers to execute arbitrary code via the archive magic version number in an 'old-style' Debian binary package, which triggered a stack-based buffer overflow (bsc#957160).

The SUSE Linux Enterprise Server 12 SP1 container image has been updated to include security and stability fixes.

The following issues related to building of the container images have been fixed:

• Included krb5 package to avoid the inclusion of krb5-mini which gets selected as a dependency by the Build Service solver. (bsc#1056193)
• Do not install recommended packages when building container images. (bsc#975726)

A number of security issues that have been already fixed by updates released for SUSE Linux Enterprise Server 12 SP1 are now included in the base image. A package/CVE cross-reference is available below.

Off-by-one error in the extracthalf function in dpkg-deb/extract.c in the dpkg-deb component in Debian dpkg 1.16.x before 1.16.17 and 1.17.x before 1.17.26 allows remote attackers to execute arbitrary code via the archive magic version number in an "old-style" Debian binary package, which triggers a stack-based buffer overflow.

Hanno Boeck discovered that the dpkg-deb tool incorrectly handled certain old style Debian binary packages. If a user or an automated system were tricked into unpacking a specially crafted binary package, a remote attacker could possibly use this issue to execute arbitrary code.
