CVE-2011-4603 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.73% chance of exploitation in the next 30 days.
