USN118-1 : postgresql vulnerabilities

Vulnerability Assessment Summary
postgresql vulnerabilities

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- libecpg-dev
- libecpg4
- libpgtcl
- libpgtcl-dev
- libpq3
- postgresql
- postgresql-client
- postgresql-contrib
- postgresql-dev
- postgresql-doc


Description :

It was discovered that unprivileged users were permited to call
internal character conversion functions. However, since these
functions were not designed to be safe against malicious choices of
argument values, this could potentially be exploited to execute
arbitrary code with the rights of the PostgreSQL server (user
"postgres"). (CVE-2005-1409)

Another vulnerability was found in the "tsearch2" module of
postgresql-contrib. This module declared several functions as
internal, although they did not accept any internal argument
this
breaks the type safety of "internal" by permiting users to construct
SQL commands that invoke other functions accepting "internal"
arguments. This could eventually be exploited to crash the server, or
possibly even execute arbitrary code with the rights of the
PostgreSQL server. (CVE-2005-1410)

These vulnerabilities must also be fixed in all existing databases
when upgrading. The post-installation script of the updated package
attempts to do this automatically
if the pack
[...]
