A vulnerability has been reported in libpng, which potentially can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an off-by-one error within the ICC profile chunk handling, which potentially can be exploited to crash an application using the library.

Note: Other chunk handling routines may be affected, too.

The vulnerability is reported in version 1.2.21. Other versions may also be affected.

Solution:
Fixed in 1.2.22 beta 2 or later.

 Maybe this is already fixed with 1.2.21-r2, see bug 194864

yes, already been fixed and the version in question was never in stable, so nothing to be done for security
