DSA-108-1 wmtv -- symlink vulnerability
- Date Reported:
- 07 Feb 2002
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2002-0247, CVE-2002-0248.
- More information:
Nicolas Boullis found some security problems in the wmtv package (a dockable video4linux TV player for windowmaker) which is distributed in Debian GNU/Linux 2.2. With the current version of wmtv, the configuration file is written back as the superuser, and without any further checks. A malicious user might use that to damage important files.
This problem has been fixed in version 0.6.5-2potato2 for the stable distribution by dropping privileges as soon as possible and only regaining them where required. In the current testing/unstable distribution this problem has been fixed in version 0.6.5-9 and above by not requiring privileges anymore. Both contain fixes for two potential buffer overflows as well.
We recommend that you upgrade your wmtv packages immediately.
- Fixed in:
Debian GNU/Linux 2.2 (potato)
- Intel ia32:
- Motorola 680x0:
- Sun Sparc:
