Description of the vulnerability
The Wireshark program captures and displays network packets. Protocols are decoded by dissectors. They are impacted by several vulnerabilities.
An attacker can generate infinite loops in the ANSI MAP, ASF, BACapp, Bluetooth HCI, IEEE 802.11, IEEE 802.3, LTP and R3 dissectors. [severity:1/4; BID-53651, CVE-2012-2392, CVE-2012-3825, CVE-2012-3826, wnpa-sec-2012-08]
An attacker can send a malformed DIAMETER packet, in order to generate a memory allocation error. [severity:1/4; BID-53652, CVE-2012-2393, wnpa-sec-2012-09]
On a SPARC or Itanium processor, an attacker can force the usage of an unaligned pointer, which stops Wireshark. [severity:1/4; 7221, BID-53653, CVE-2012-2394, wnpa-sec-2012-10]Complete Vigil@nce bulletin....
