SUSE CVE-2009-2560

Multiple unspecified vulnerabilities in Wireshark 1.2.0 allow remote attackers to cause a denial of service application crash via a file that records a malformed packet trace and is processed by the 1 Bluetooth L2CAP, 2 RADIUS, or 3 MIOP dissector. NOTE: it was later reported that the RADIUS issu...

SUSE CVE-2011-2497

Integer underflow in the l2capconfigreq function in net/bluetooth/l2capcore.c in the Linux kernel before 3.0 allows remote attackers to cause a denial of service heap memory corruption or possibly have unspecified other impact via a small command-size value within the command header of a Logical...

SUSE CVE-2016-7957

In Wireshark 2.2.0, the Bluetooth L2CAP dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-btl2cap.c by avoiding use of a seven-byte memcmp for potentially shorter strings...
