Buffer overflow in TestChip function in XFree86 SuperProbe in Slackware Linux 3.1 allows local users to gain root privileges via a long -nop
Noroxi assessment
Priority: Monitor (action score 28/100)
- Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 1% (FIRST EPSS); higher than 63.9% of all records.
- No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.
