Synopsis ========
A directory traversal vulnerability has been discovered in Star.
Background ==========
The Star program provides the ability to create and extract tar archives.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/star < 1.5_alpha84 >= 1.5_alpha84
Description ===========
Robert Buchholz of the Gentoo Security team discovered a directory traversal vulnerability in the has_dotdot() function which does not identify //.. (slash slash dot dot) sequences in file names inside tar files.
Impact ======
By enticing a user to extract a specially crafted tar archive, a remote attacker could extract files to arbitrary locations outside of the specified directory with the permissions of the user running Star.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Star users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/star-1.5_alpha84"
