Vigil@nce - PostgreSQL: read-write access via make check
March 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
When "make check" is run, a local attacker can access to
PostgreSQL, in order to read or alter data.
Impacted products: Debian, PostgreSQL
Severity: 2/4
Creation date: 20/02/2014
DESCRIPTION OF THE VULNERABILITY
The PostgreSQL product has a test suite, which is run via the
"make test" command.
However, during these tests, the access to the local socket is set
to "trust", which means that a local user can connect with no
authentication.
When "make check" is run, a local attacker can therefore access to
PostgreSQL, in order to read or alter data.
