Critical Nessus Plugin ID 37292
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionUlf Harnhammar discovered several vulnerabilities in GNU Anubis.
- Unsafe uses of `sscanf'. The `%s' format specifier is used, which allows a classical buffer overflow. (auth.c)
- Format string bugs invoking `syslog'. (log.c, errs.c, ssl.c)
Ulf notes that these vulnerabilities can be exploited by a malicious IDENT server as a denial-of-service attack.
SolutionUpdate the affected package.
