Уязвимость утилиты архивирования Сpio, связанная с ошибками при проверке заголовка TAR-файла, позволяющая нарушителю повысить свои привилегии

Уязвимость компонента dstring.c пакета cpio операционной системы Debian GNU/Linux, позволяющая нарушителю выполнить произвольный код через созданный файл

Уязвимость двоичного архиватора cpio, связанная с неправильным ограничением имени пути к ограниченному каталогу, позволяющая нарушителю вызвать отказ в обслуживании

In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives. When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system.

GNU cpio through 2.13 allows attackers to execute arbitrary code via a crafted pattern file, because of a dstring.c ds_fgetstr integer overflow that triggers an out-of-bounds heap write. NOTE: it is unclear whether there are common cases where the pattern file, associated with the -E option, is untrusted data.

Debian's cpio contains a path traversal vulnerability. This issue was introduced by reverting CVE-2015-1197 patches which had caused a regression in --no-absolute-filenames. Upstream has since provided a proper fix to --no-absolute-filenames.
