Background ========== Vobcopy is a tool for decrypting and copying DVD .vob files to a hard disk. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-video/vobcopy < 1.1.0 >= 1.1.0 Description =========== Joey Hess reported that vobcopy appends data to the file "/tmp/vobcopy.bla" in an insecure manner. Impact ====== A local attacker could exploit this vulnerability to conduct symlink attacks and append data to arbitrary files with the privileges of the user running Vobcopy. Workaround ========== There is no known workaround at this time.
