CVE-2011-1959

Severity CVSS v4.0:
Pending analysis
Type:
CWE-119 Buffer Errors
Publication date:

Description

The snoop_read function in wiretap/snoop.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 does not properly handle certain virtualizable buffers, which allows remote attackers to cause a denial of service (application crash) via a large length value in a snoop file that triggers a stack-based buffer over-read.
