A memory leak was found in the way libpng processed malformed Portable Network Graphics (PNG) images with Physical Scale (sCAL) extension. A remote attacker could create a specially-crafted PNG image and trick the local user into opening it in an application, using the libpng library, leading to denial of service (relevant libpng-based application crash).

CVE Request: [2] http://www.openwall.com/lists/oss-security/2010/06/28/2
The pngsettext2 function in pngset.c in libpng 1.0.x before 1.0.59, 1.2.x before 1.2.49, 1.4.x before 1.4.11, and 1.5.x before 1.5.10 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted text chunk in a PNG image file, which triggers a memory allocation failure that is not properly handled, leading to a heap-based buffer overflow.
dnsjava is vulnerable to a denial of service, caused by an error when using the ValidatingResolver for DNSSEC validation. By using specially crafted DNSSEC-signed zones, an attacker could exploit this vulnerability to exhaust all available CPU resources.
Heap-based buffer overflow in the pngcombinerow function in libpng before 1.5.21 and 1.6.x before 1.6.16, when running on 64-bit systems, might allow context-dependent attackers to execute arbitrary code via a "very wide interlaced" PNG image.
Buffer overflow in the pngreadIDATdata function in pngrutil.c in libpng before 1.5.21 and 1.6.x before 1.6.16 allows context-dependent attackers to execute arbitrary code via IDAT data with a large width, a different vulnerability than CVE-2014-9495.
A type conversion flaw leading to an out-of-bounds heap buffer read was found in the way libpng, a library of functions for manipulation PNG image format files, performed expansion of certain iCCP, iTXt, and zTXt PNG image file chunks.
A remote attacker could provide a specially-crafted Portable Network Graphics (PNG) image file, which once opened in an application, linked against libpng, could lead to denial of service or in some cases, execution of arbitrary code with permission of the user running such an application.

A vulnerability was found in libpng 1.6.36. The function pngimagefree in png.c has a use-after-free because pngimagefreefunction is called under pngsafeexecute.

Buffer overflow in pngpread.c in libpng before 1.2.44 and 1.4.x before 1.4.3, as used in progressive applications, might allow remote attackers to execute arbitrary code via a PNG image that triggers an additional data row.
A flaw was found in libpng 1.6.38. A crafted PNG image can lead to a segmentation fault and denial of service in pngsetuppaethrow() function.
Memory leak in pngwutil.c in libpng 1.2.13beta1, and other versions before 1.2.15beta3, allows context-dependent attackers to cause a denial of service (memory leak or segmentation fault) via a JPEG image containing an iCCP chunk with a negative embedded profile length.
Multiple off-by-one errors in libpng before 1.2.32beta01, and 1.4 before 1.4.0beta34, allow context-dependent attackers to cause a denial of service (crash) or have unspecified other impact via a PNG image with crafted zTXt chunks, related to (1) the pngpushreadzTXt function in pngread.c, and possibly related to (2) pngtest.c.
libpng 1.0.6 through 1.0.32, 1.2.0 through 1.2.26, and 1.4.0beta01 through 1.4.0beta19 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a PNG file with zero length "unknown" chunks, which trigger an access of uninitialized memory.
Off-by-one error in the pngformattedwarning function in pngerror.c in libpng 1.5.4 through 1.5.7 might allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via unspecified vectors, which trigger a stack-based buffer overflow.
Buffer overflow in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4, when used by an application that calls the pngrgbtogray function but not the pngsetexpand function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have unspecified other impact, via a crafted PNG image.
It was found that in libpng, prior to 1.2.45, the error function received a NULL pointer, expressed erroneously as '\0', instead of the empty string "". This error was introduced in libpng-1.2.20, and pngdefaulterror() will crash in this case.
This was be fixed in libpng-1.5.4, libpng-1.4.8, libpng-1.2.45, and libpng-1.0.55.

It was found that libpng read uninitialized memory when it encountered a sCAL chunk that is empty, and improperly handles a sCAL chunk that lacks the terminating zero between the two strings that it conveys.
This was fixed in libpng-1.5.4, libpng-1.4.8, libpng-1.2.45, and libpng-1.0.55.

It was reported [1] that the fix for CVE-2004-0421 in libpng was inadvertently reverted during the 1.2.23 development cycle. The original flaw could be used to cause a denial of service via a carefully-crafted PNG image.
This would affect all versions of libpng >=1.2.23, including 1.4.x and 1.5.x.

pngrtran.c in libpng 1.5.x before 1.5.1 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted palette-based PNG image that triggers a buffer overflow, related to the pngdoexpandpalette function, the pngdorgbtogray function, and an integer underflow. NOTE: some of these details are obtained from third party information.
Buffer overflow vulnerabilities in functions pnggetPLTE/pngsetPLTE, allowing remote attackers to cause DoS to application or have unspecified other impact. These functions failed to check for an out-of-range palette when reading or writing PNG files with a bitdepth 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.
Affected versions of libpng are before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19.

Unspecified vulnerability in libpng before 1.6.20, as used in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-07-01, allows attackers to gain privileges via a crafted application, as demonstrated by obtaining Signature or SignatureOrSystem access, aka internal bug 23265085.
An issue has been found in third-party PNM decoding associated with libpng 1.6.35. It is a stack-based buffer overflow in the function gettoken in pnm2png.c in pnm2png.
An issue was discovered in the libp2p-core crate before 0.8.1 for Rust. Attackers can spoof ed25519 signatures.
An issue was discovered in the libp2p-deflate crate before 0.27.1 for Rust. An uninitialized buffer is passed to AsyncRead::pollread(), which is a user-provided trait function.
A vulnerability was reported in Libpng where the input buffer might not have the same length as the pre-defined value hardcoded in the pngimage so that the index is out of bound in the later loop.
