Stack-based Buffer Over-read Vulnerability in Wireshark's snoop_read Function

CVE-2011-1959 · MEDIUM Severity

AV:N/AC:M/AU:N/C:N/I:N/A:P

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.
