** DISPUTED ** png_create_info_struct in png.c in libpng 1.6.36 has a memory leak, as demonstrated by pngcp. NOTE: a third party has stated "I don't think it is libpng's job to free this buffer."
CVE-2010-2249 8 Apple, Canonical, Debian and 5 more 12 Iphone Os, Itunes, Safari and 9 more 2020-08-14 4.3 MEDIUM 6.5 MEDIUM
Memory leak in pngrutil.c in libpng before 1.2.44, and 1.4.x before 1.4.3, allows remote attackers to cause a denial of service (memory consumption and application crash) via a PNG image containing malformed Physical Scale (aka sCAL) chunks.
CVE-2010-1205 10 Apple, Canonical, Debian and 7 more 17 Iphone Os, Itunes, Mac Os X and 14 more 2020-08-14 7.5 HIGH 9.8 CRITICAL
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.
CVE-2010-0205 7 Apple, Canonical, Debian and 4 more 7 Mac Os X, Ubuntu Linux, Debian Linux and 4 more 2020-08-07 4.3 MEDIUM N/A
The png_decompress_chunk function in pngrutil.c in libpng 1.0.x before 1.0.53, 1.2.x before 1.2.43, and 1.4.x before 1.4.1 does not properly handle compressed ancillary-chunk data that has a disproportionately large uncompressed representation, which allows remote attackers to cause a denial of service (memory and CPU consumption, and application hang) via a crafted PNG file, as demonstrated by use of the deflate compression method on data composed of many occurrences of the same character, related to a "decompression bomb" attack.
CVE-2011-2692 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2020-08-06 6.8 MEDIUM 8.8 HIGH
The png_handle_sCAL function in pngrutil.c 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 does not properly handle invalid sCAL chunks, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted PNG image that triggers the reading of uninitialized memory.
CVE-2011-2691 3 Debian, Fedoraproject, Libpng 3 Debian Linux, Fedora, Libpng 2020-08-06 4.3 MEDIUM 6.5 MEDIUM
The png_err function in pngerror.c 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 makes a function call using a NULL pointer argument instead of an empty-string argument, which allows remote attackers to cause a denial of service (application crash) via a crafted PNG image.
CVE-2011-2690 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2020-08-06 6.8 MEDIUM 8.8 HIGH
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 png_rgb_to_gray function but not the png_set_expand function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have unspecified other impact, via a crafted PNG image.
CVE-2011-2501 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2020-08-06 4.3 MEDIUM 6.5 MEDIUM

NOTE: this vulnerability exists because of a CVE-2004-0421 regression. NOTE: this is called an off-by-one error by some sources.
CVE-2011-3045 6 Debian, Fedoraproject, Google and 3 more 13 Debian Linux, Fedora, Chrome and 10 more 2020-04-14 6.8 MEDIUM N/A
Integer signedness error in the png_inflate function in pngrutil.c in libpng before 1.4.10beta01, as used in Google Chrome before 17.0.963.83 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file, a different vulnerability than CVE-2011-3026.
CVE-2017-12652 1 Libpng 1 Libpng 2019-09-17 7.5 HIGH 9.8 CRITICAL
libpng before 1.6.32 does not properly check the length of chunks against the user limit.
CVE-2008-5907 2 Debian, Libpng 2 Debian Linux, Libpng 2018-11-08 5.0 MEDIUM N/A
The png_check_keyword function in pngwutil.c in libpng before 1.0.42, and 1.2.x before 1.2.34, might allow context-dependent attackers to set the value of an arbitrary memory location to zero via vectors involving creation of crafted PNG files with keywords, related to an implicit cast of the '\0' character constant to a NULL pointer. NOTE: some sources incorrectly report this as a double free vulnerability.
CVE-2012-3425 5 Canonical, Debian, Libpng and 2 more 5 Ubuntu Linux, Debian Linux, Libpng and 2 more 2018-10-30 4.3 MEDIUM N/A
