Description

Chris Evans discovered several vulnerabilities in libpng :

  • CAN-2004-0597 Multiple buffer overflows exist, including when handling transparency chunk data, which could be exploited to cause arbitrary code to be executed when a specially crafted PNG image is processed

  • CAN-2004-0598

    Multiple NULL pointer dereferences in png_handle_iCPP() and elsewhere could be exploited to cause an application to crash when a specially crafted PNG image is processed

  • CAN-2004-0599

    Multiple integer overflows in the png_handle_sPLT(), png_read_png() functions and elsewhere could be exploited to cause an application to crash, or potentially arbitrary code to be executed, when a specially crafted PNG image is processed

In addition, a bug related to CAN-2002-1363 was fixed :

  • CAN-2004-0768

    A buffer overflow could be caused by incorrect calculation of buffer offsets, possibly leading to the execution of arbitrary code
