GNU tar: Buffer overflow

GNU tar: Buffer overflow A malicious tar archive could trigger a Buffer overflow in GNU tar, potentially resulting in the execution of arbitrary code. tar March 10, 2006 March 10, 2006: 01 123038 remote 1.15.1-r1 1.15.1-r1

GNU tar is the standard GNU utility for creating and manipulating tar archives, a common format used for creating backups and distributing files on UNIX-like systems.

Jim Meyering discovered a flaw in the handling of certain header fields that could result in a buffer overflow when extracting or listing the contents of an archive.

A remote attacker could construct a malicious tar archive that could potentially execute arbitrary code with the privileges of the user running GNU tar.

There is no known workaround at this time.

All GNU tar users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-arch/tar-1.15.1-r1"
