Scientific Linux Security Update : postgresql and postgresql84 on SL4.x, SL5.x i386/x86_64
Medium Nessus Plugin ID 60862
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionIt was discovered that a user could utilize the features of the PL/Perl and PL/Tcl languages to modify the behavior of a SECURITY DEFINER function created by a different user. If the PL/Perl or PL/Tcl language was used to implement a SECURITY DEFINER function, an authenticated database user could use a PL/Perl or PL/Tcl script to modify the behavior of that function during subsequent calls in the same session. This would result in the modified or injected code also being executed with the privileges of the user who created the SECURITY DEFINER function, possibly leading to privilege escalation.
For Scientific Linux 4, the updated postgresql packages upgrade PostgreSQL to version 7.4.30.
For Scientific Linux 5, the updated postgresql packages upgrade PostgreSQL to version 8.1.22, and the updated postgresql84 packages upgrade PostgreSQL to version 8.4.5.
If the postgresql service is running, it will be automatically restarted after installing this update.
SolutionUpdate the affected packages.
