Vobcopy uses temporary files in an insecure manner, allowing for a symlink attack.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-video/vobcopy | * | < 1.1.0 | >= 1.1.0 |
Vobcopy is a tool for decrypting and copying DVD .vob files to a hard disk.
Joey Hess reported that vobcopy appends data to the file "/tmp/vobcopy.bla" in an insecure manner.
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.
There is no known workaround at this time.
All Vobcopy users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-video/vobcopy-1.1.0"
