Mandriva Linux Security Advisory 2011-040
Posted Mar 3, 2011

Mandriva Linux Security Advisory 2011-040 - 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. The updated packages have been patched to correct this issue.
