PostgreSQL is an open source object-relational database management system.
Multiple vulnerabilities have been discovered in PostgreSQL. Please review the referenced CVE identifiers for details.
In addition it was discovered that Gentoo’s PostgreSQL installation suffered from a privilege escalation vulnerability due to a runscript which called OpenRC’s checkpath() on a user controlled path and allowed user running PostgreSQL to kill arbitrary processes via PID file manipulation.
A remote attacker could bypass certain client-side connection security features, read arbitrary server memory or alter certain data.
In addition, a local attacker could gain privileges or cause a Denial of Service condition by killing arbitrary processes.
There is no known workaround at this time.
