CVE-2011-3184

Pidgin < 2.10.0 - Denial of Service via MSN HTTP 100 Response Handling

Title source: llm
STIX 2.1

Description

The msn_httpconn_parse_data function in httpconn.c in the MSN protocol plugin in libpurple in Pidgin before 2.10.0 does not properly handle HTTP 100 responses, which allows remote attackers to cause a denial of service (incorrect memory access and application crash) via vectors involving a crafted server message.
