CVE-2011-4603
Pidgin < 2.10.1 - Denial of Service via SILC Protocol Message Handling
Title source: llmDescription
The silc_channel_message function in ops.c in the SILC protocol plugin in libpurple in Pidgin before 2.10.1 does not perform the expected UTF-8 validation on message data, which allows remote attackers to cause a denial of service (application crash) via a crafted message, a different vulnerability than CVE-2011-3594.
