Description

The remote host is affected by the vulnerability described in GLSA-201612-07 (dpkg: Arbitrary code execution)

 Gentoo Linux developer, Hanno Böck, discovered an off-by-one error in the dpkg-deb component of dpkg, the Debian package management system, which triggers a stack-based buffer overflow.

 # emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/dpkg-1.17.26'
