Red Hat Product Errata RHSA-2011:1820 0 normal SHIPPED_LIVE Moderate: pidgin security update 2011-12-14 23:59:45 UTC

Description Huzaifa S. Sidhpurwala 2011-12-12 04:54:54 UTC 
When receiving various incoming messages, the SILC protocol plugin failed to validate that a piece of text was UTF-8. In some cases invalid UTF-8 data would lead to a crash. This vulnerability is similar to CVE-2011-3594, but occurs in a different piece of code and was fixed at a later date.
