Red Hat Product Errata RHSA-2014:0139 0 normal SHIPPED_LIVE Moderate: pidgin security update 2014-02-05 22:42:24 UTC

Description Huzaifa S. Sidhpurwala 2014-01-23 07:22:28 UTC 
Multiple null-pointer dereferences were found in the MSN protocol plugin. Details as follows:

- NULL pointer dereference when parsing headers in MSN protocol plugin.
- NULL pointer dereference when parsing OIM data in MSN protocol plugin.
- NULL pointer dereference when parsing SOAP data in MSN protocol plugin.

If a remote server provided a specially-crafted MSN message, it could cause pidgin to crash.
