CUPS (Common UNIX Printing System) Denial of Service Vulnerability
Certain versions of the CUPS (Common UNIX Printing System) are vulnerable to Denial of Service attacks which result in disruption of print services. These attacks may be buffer overflow attacks which result in root access. The information available currently is not robust enough to come to a definitive conclusion.
The problems as listed in the CUPS 1.0.5 Denial of Service Patch Set #1 - 06/16/2000 are:
- Malformed IPP requests could crash cupsd.
- Standard CGI form POSTs could crash cupsd.
- The cupsd program did not always delete request files when needed.
- Authenticating with a non-existent user or a user with no shadow password could crash cupsd.
