- More information:
Michal Marek discovered that ruby-archive-tar-minitar, a Ruby library that provides the ability to deal with POSIX tar archive files, is prone to a directory traversal vulnerability. An attacker can take advantage of this flaw to overwrite arbitrary files during archive extraction via a .. (dot dot) in an extracted filename.
For the stable distribution (jessie), this problem has been fixed in version 0.5.2-2+deb8u1.
We recommend that you upgrade your ruby-archive-tar-minitar packages.
