Description Martin Prpič 2015-02-03 14:30:58 UTC
The PostgreSQL project reports the following issue:

Errors in memory size tracking within the pgcrypto module permitted stack buffer overruns and improper dependence on the contents of uninitialized memory. The buffer overrun cases can crash the server, and we have not ruled out the possibility of attacks that lead to privilege escalation.

Red Hat would like to thank the PostgreSQL project for reporting this issue. Upstream acknowledges Marko Tiikkaja as the original reporter.
