VuXML IDDescription
262b92fe-81c8-11e1-8899-001ec9578670png -- memory corruption/possible remote code execution

The PNG project reports:

libpng fails to correctly handle malloc() failures for text chunks (in png_set_text_2()), which can lead to memory corruption and the possibility of remote code execution.

57c705d6-12ae-11dd-bab7-0016179b2dd5png -- unknown chunk processing uninitialized memory access

Secunia reports:

Tavis Ormandy has reported a vulnerability in libpng, which can be exploited by malicious people to cause a Denial of Service, disclose potentially sensitive information, or potentially compromise an application using the library.

The vulnerability is caused due to the improper handling of PNG chunks unknown to the library. This can be exploited to trigger the use of uninitialized memory in e.g. a free() call via unknown PNG chunks having a length of zero.

Successful exploitation may allow execution of arbitrary code, but requires that the application calls the png_set_read_user_chunk_fn() function or the png_set_keep_unknown_chunks() function under specific conditions.

172acf78-780c-11dc-b3f4-0016179b2dd5png -- multiple vulnerabilities

A Secunia Advisory reports:

Some vulnerabilities have been reported in libpng, which can be exploited by malicious people to cause a DoS (Denial of Service).

Certain errors within libpng, including a logical NOT instead of a bitwise NOT in pngtrtran.c, an error in the 16bit cheap transparency extension, and an incorrect use of sizeof() may be exploited to crash an application using the library.

Various out-of-bounds read errors exist within the functions png_handle_pCAL(), png_handle_sCAL(), png_push_read_tEXt(), png_handle_iTXt(), and png_handle_ztXt(), which may be exploited by exploited to crash an application using the library.

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.

CVE-2007-5269
edef3f2f-82cf-11df-bcce-0018f3e2eb82png -- libpng decompression buffer overflow

The PNG project describes the problem in an advisory:

Several versions of libpng through 1.4.2 (and through 1.2.43 in the older series) contain a bug whereby progressive applications such as web browsers (or the rpng2 demo app included in libpng) could receive an extra row of image data beyond the height reported in the header, potentially leading to an out-of-bounds write to memory (depending on how the application is written) and the possibility of execution of an attacker's code with the privileges of the libpng user (including remote compromise in the case of a libpng-based browser visiting a hostile web site).

c564f9bd-8ba7-11e4-801f-0022156e8794png -- heap overflow for 32-bit builds

32-bit builds of PNG library are vulnerable to an unsigned integer overflow that is triggered by a crafted wide interlaced images. Overflow results in a heap corruption that will crash the application and may lead to the controlled overwrite of a selected portions of process address space.

1886e195-8b87-11e5-90e7-b499baebfeaflibpng buffer overflow in png_set_PLTE

libpng reports:

CVE for a vulnerability in libpng, all versions, in the png_set_PLTE/png_get_PLTE functions. These functions failed to check for an out-of-range palette when reading or writing PNG files with a bit_depth less than 8. Some applications might read the bit depth from the IHDR chunk and allocate memory for a 2^N entry palette, while libpng can return a palette with up to 256 entries even when the bit depth is less than 8.
