Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2016-2530

Severity Medium
Score 5.9/10

Summary

The dissct_rsl_ipaccess_msg function in epan/dissectors/packet-rsl.c in the RSL dissector in Wireshark 1.12.x before 1.12.10 and 2.0.x before 2.0.2 mishandles the case of an unrecognized TLV type, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet, a different vulnerability than CVE-2016-2531.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
