RHBA-2011:1538 - Bug Fix Advisory

Topic

An updated libXcursor package that fixes a bug is now available for Red Hat
Enterprise Linux 5.

Description

The X.Org's X11 libXcursor runtime library for cursor management.

This updated libXcursor package fixes the following bug:

• Prior to this update, libXcursor allocated memory to store the comment and

fileheader associated with the cursor data but due to an inversion in the logic,
which would not free the memory if the associated pointer was not NULL, this
allocated memory was never freed. Consequently this caused a memory leak each
time a cursor was created or loaded with libXcursor. This update fixes the
internal logic, the data is freed as required when the pointer is set, and the
memory leaks no longer occur in the scenario described. (BZ#688657)

All users of libXcursor are advised to upgrade to this updated package, which
fixes this bug.
