FreeBSD : pango -- integer overflow (4b172278-3f46-11de-becb-001cc0377035)

Medium Nessus Plugin ID 38751


The remote FreeBSD host is missing one or more security-related updates.


oCERT reports :

Pango suffers from a multiplicative integer overflow which may lead to a potentially exploitable, heap overflow depending on the calling conditions.

For example, this vulnerability is remotely reachable in Firefox by creating an overly large document.location value but only results in a process-terminating, allocation error (denial of service).

The affected function is pango_glyph_string_set_size. An overflow check when doubling the size neglects the overflow possible on the subsequent allocation.


Update the affected packages.
