GLSA-200505-12 : PostgreSQL: Multiple vulnerabilities
High Nessus Plugin ID 18271
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200505-12 (PostgreSQL: Multiple vulnerabilities)
PostgreSQL gives public EXECUTE access to a number of character conversion routines, but doesn't validate the given arguments (CAN-2005-1409). It has also been reported that the contrib/tsearch2 module of PostgreSQL misdeclares the return value of some functions as 'internal' (CAN-2005-1410).
An attacker could call the character conversion routines with specially setup arguments to crash the backend process of PostgreSQL or to potentially gain administrator rights. A malicious user could also call the misdeclared functions of the contrib/tsearch2 module, resulting in a Denial of Service or other, yet uninvestigated, impacts.
There is no known workaround at this time.
SolutionAll PostgreSQL users should update to the latest available version and follow the guide at http://www.postgresql.o rg/about/news.315 # emerge --sync # emerge --ask --oneshot --verbose dev-db/postgresql
