Debian DSA-3677-1 : libarchive - security update

High Nessus Plugin ID 93695

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities were discovered in libarchive, a multi-format archive and compression library, which may lead to denial of service (memory consumption and application crash), bypass of sandboxing restrictions and overwrite arbitrary files with arbitrary data from an archive, or the execution of arbitrary code.

Solution

Upgrade the libarchive packages.

For the stable distribution (jessie), these problems have been fixed in version 3.1.2-11+deb8u3.
