Debian DSA-3476-1 : postgresql-9.4 - security update
High Nessus Plugin ID 88727
SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral vulnerabilities have been found in PostgreSQL-9.4, a SQL database system.
- CVE-2016-0766 A privilege escalation vulnerability for users of PL/Java was discovered. Certain custom configuration settings (GUCs) for PL/Java will now be modifiable only by the database superuser to mitigate this issue.
- CVE-2016-0773 Tom Lane and Greg Stark discovered a flaw in the way PostgreSQL processes specially crafted regular expressions. Very large character ranges in bracket expressions could cause infinite loops or memory overwrites. A remote attacker can exploit this flaw to cause a denial of service or, potentially, to execute arbitrary code.
SolutionUpgrade the postgresql-9.4 packages.
For the stable distribution (jessie), these problems have been fixed in version 9.4.6-0+deb8u1.
