CVE-2018-11362 [HIGH] CWE-125 wireshark: Out-of-bounds read in packet-ldss.c
wireshark: Out-of-bounds read in packet-ldss.c
In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the LDSS dissector could crash. This was addressed in epan/dissectors/packet-ldss.c by avoiding a buffer over-read upon encountering a missing '\0' character.
A heap-based buffer overflow was found in the wireshark module responsible for analyzing the LDSS protocol. An attacker could create a malicious LDSS message to cause a remote denial of service, crashing the application.
