|Bugzilla:||907892: CVE-2013-0255 postgresql: array indexing error in enum_recv()|
The MITRE CVE dictionary describes this issue as:
PostgreSQL 9.2.x before 9.2.3, 9.1.x before 9.1.8, 9.0.x before 9.0.12, 8.4.x before 8.4.16, and 8.3.x before 8.3.23 does not properly declare the enum_recv function in backend/utils/adt/enum.c, which causes it to be invoked with incorrect arguments and allows remote authenticated users to cause a denial of service (server crash) or read sensitive process memory via a crafted SQL command, which triggers an array index error and an out-of-bounds read.
This issue did not affect the version of postgresql, as shipped with Red Hat Enterprise Linux 5. This issue affects the version of postgresql84, as shipped with Red Hat Enterprise Linux 5 and the version of postgresql, as shipped with Red Hat Enterprise Linux 6.
