Fedora 14 : pango-1.28.1-5.fc14 (2011-3194)

medium Nessus Plugin ID 52696

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

It was discovered that pango did not check for memory reallocation failures in hb_buffer_ensure() function. This could trigger a NULL pointer dereference in hb_buffer_add_glyph(), where possibly untrusted input is used as an index used for accessing members of the incorrectly reallocated array, resulting in the use of NULL address as the base array address. This can result in application crash or, possibly, code execution.

It was demonstrated that it's possible to trigger this flaw in Firefox via a specially crafted web page.
