Descriptions

The cpio_safer_name_suffix function in util.c in cpio 2.11 allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted cpio file.

La función cpio_safer_name_suffix en util.c en cpio 2.11 permite a atacantes remotos causar una denegación de servicio (escritura fuera de rango) através de un archivo cpio manipulado.

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.
