Patch for CUPS 1.3 by Michael Sweet
CUPS 1.1 is not affected by "one null byte overwrite" mentioned in Secunia advisory, that part only affects CUPS 1.2+. Attacker can only overwrite memory location 2^16 bytes away from current stack location towards the bottom of the stack. Patch for CUPS 1.1 adds additional checks on input values. Without them, it may still be possible to trick cupsd to read some random data from stack and possibly crash daemon. now public, removing embargo http://secunia.com/secunia_research/2007-76/advisory/ cups-1.3.4-2.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report. |
