A vulnerability has been reported in libpng, which can be exploited by malicious people to cause a DoS (Denial of Service) or to potentially compromise an application using the library.
The vulnerability is caused due to the library improperly initialising certain pointer arrays prior to freeing array elements in case the application runs out of memory. This can potentially be exploited to cause a memory corruption via a specially crafted PNG file.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is reported in versions prior to 1.0.43 and 1.2.35.
