1) Resource management error (CVE-ID: CVE-2011-3184)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
