- Chris Evans discovered several vulnerabilities in libpng:
- 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
- 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
- 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:
- A buffer overflow could be caused by incorrect
- calculation of buffer offsets, possibly leading to the execution of
- arbitrary code
- For the current stable distribution (woody), these problems have been
- fixed in libpng3 version 1.2.1-1.1.woody.7 and libpng version
- 1.0.12-3.woody.7.
- For the unstable distribution (sid), these problems will be fixed soon.
- We recommend that you update your libpng and libpng3 packages.
