FreeBSD : GNU Anubis buffer overflows and format string vulnerabilities (8471bb85-6fb0-11d8-873f-0020ed76ef5a)

Critical Nessus Plugin ID 37292


The remote FreeBSD host is missing a security-related update.


Ulf 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.


Update the affected package.
