Impact

If Wireshark is launched manually by a user with Advanced Shell ( bash ) access, dissection of specially crafted packets could cause Wireshark to consume excessive resources. Wireshark is not part of normal BIG-IP operation; only users who actively run Wireshark are vulnerable.

Multiple vulnerabilities were discovered in the dissectors/parsers for PKTC, IAX2, GSM CBCH and NCP which could result in denial of service.

This update also fixes many older less important issues by updating the package to the version found in Debian 8 also known as Jessie.

For Debian 7 'Wheezy', these problems have been fixed in version 1.12.1+g01b65bf-4+deb8u6~deb7u1.

We recommend that you upgrade your wireshark packages.
