CVE-2011-4603 · MEDIUM Severity

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

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.
