Subject: CVE request: Wireshark multiple vulnerabilities
According to secunia advisory: https://secunia.com/advisories/47494/ :
Multiple vulnerabilities have been reported in Wireshark, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
compromise a user's system.
1) NULL pointer dereference errors when reading certain packet information can
be exploited to cause a crash.
2) An error within the RLC dissector can be exploited to cause a buffer
overflow via a specially crafted RLC packet capture file.
and according with upstream advisory:
1)http://www.wireshark.org/security/wnpa-sec-2012-01.html
Name: Multiple Wireshark file parser vulnerabilities
