Title: Socks5 1.0r5 Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
A buffer overflow exists in certain versions of sock5, which could allow a local user to use any setuid binary compiled against the socks5 library to gain root access. The code in question involves filling a buffer of fixed size via the vsprintf() call. By setting the proper enviroment variables, a user could cause the return address on the stack to be overwritten, and arbitrary code run with root privelege.
Affected Products:
- NEC socks5 1.0.0 r5
