U radu programskog paketa PostgreSQL, namijenjenog operacijskom sustavu Debian, uočena je sigurnosna nepravilnost čija je ispravka uključena u nove inačice. Propust nastaje uslijed neodgovarajuće obrade pojedinih ulaznih podataka u datoteci "contrib/intarray/_int_bool.c". Uspješna zloupotreba, izvršena podmetanjem posebno oblikovanih brojeva, može rezultirati mogućnošću izvođenja napada uskraćivanja usluge ili pokretanja proizvoljnog programskog koda. Svim korisnicima paketa savjetuje se pravovremena instalacija dostupne programske nadogradnje.

Package        : postgresql-8.3, postgresql-8.4, postgresql-9.0
Vulnerability  : buffer overflow
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2010-4015

It was discovered that PostgreSQL's intarray contrib module does not
properly handle integers with a large number of digits, leading to a
server crash and potentially arbitary code execution.

For the stable distribution (lenny), this problem has been fixed in
version 8.3.14-0lenny1 of the postgresql-8.3 package.

For the testing distribution (squeeze), this problem has been fixed in
version 8.4.7-0squeeze1 of the postgresql-8.4 package.

For the unstable distribution (sid), this problem has been fixed in
version 8.4.7-1 of the postgresql-8.4 package and version 9.0.3-1 of
the postgresql-9.0 package.

The updates also include reliability improvements; for details see the
respective changelogs.

We recommend that you upgrade your PostgreSQL packages.
