Synopsis ========
A buffer overflow flaw in GNU Tar could result in execution of arbitrary code or a Denial of Service.
Background ==========
GNU Tar is a utility to create archives as well as add and extract files from archives.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/tar < 1.23 >= 1.23
Description ===========
GNU Tar is vulnerable to a boundary error in the rmt_read__ function in lib/rtapelib.c, which could cause a heap-based buffer overflow.
Impact ======
A remote attacker could entice the user to load a specially crafted archive, possibly resulting in the execution of arbitrary code or a Denial of Service.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All GNU Tar users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/tar-1.23"
NOTE: This is a legacy GLSA. Updates for all affected architectures are available since July 18, 2010. It is likely that your system is already no longer affected by this issue.
