This advisory updates wireshark to the latest version , fixing one security issue: Heap-based buffer overflow in the dissect_ldss_transfer function in the LDSS dissector in Wireshark 1.2.0 through 1.2.12 and 1.4.0 through 1.4.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via an LDSS packet with a long digest line that triggers memory corruption .
