Ubuntu Security Notice 2906-1 - Alexander Cherepanov discovered that GNU cpio incorrectly handled symbolic links when used with the --no-absolute-filenames option. If a user or automated system were tricked into extracting a specially-crafted cpio archive, a remote attacker could possibly use this issue to write arbitrary files. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Gustavo Grieco discovered that GNU cpio incorrectly handled memory when extracting archive files. If a user or automated system were tricked into extracting a specially-crafted cpio archive, a remote attacker could use this issue to cause GNU cpio to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
