Buffer overflow in Microsoft Telnet client in Windows 95 and Windows 98 via a malformed Telnet argument.
Noroxi assessment
Priority: Monitor (action score 12/100)
- 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: 7.9% (FIRST EPSS); higher than 94.6% of all records.
- Special conditions such as timing or configuration are required.
- 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.
