Wireshark is a program for monitoring network traffic.
Bugs were found in Wireshark's SCSI and SSCOP protocol dissectors. Ethereal could crash or stop responding if it read a malformed packet off the network. (CVE-2006-4330, CVE-2006-4333)
An off-by-one bug was found in the IPsec ESP decryption preference parser. Ethereal could crash or stop responding if it read a malformed packet off the network. (CVE-2006-4331)
Users of Wireshark or Ethereal should upgrade to these updated packages containing Wireshark version 0.99.3, which is not vulnerable to these issues. These packages also fix a bug in the PAM configuration of the Wireshark packages which prevented non-root users starting a capture.
