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 png_push_read_zTXt function in pngread.c, and possibly related to (2) pngtest.c.
CVE-2015-8540 4 Debian, Fedoraproject, Libpng and 1 more 7 Debian Linux, Fedora, Libpng and 4 more 2021-06-29 9.3 HIGH 8.8 HIGH
Integer underflow in the png_check_keyword function in pngwutil.c in libpng 0.90 through 0.99, 1.0.x before 1.0.66, 1.1.x and 1.2.x before 1.2.56, 1.3.x and 1.4.x before 1.4.19, and 1.5.x before 1.5.26 allows remote attackers to have unspecified impact via a space character as a keyword in a PNG image, which triggers an out-of-bounds read.
CVE-2016-10087 1 Libpng 1 Libpng 2021-06-29 5.0 MEDIUM 7.5 HIGH
The png_set_text_2 function in libpng 0.71 before 1.0.67, 1.2.x before 1.2.57, 1.4.x before 1.4.20, 1.5.x before 1.5.28, and 1.6.x before 1.6.27 allows context-dependent attackers to cause a NULL pointer dereference vectors involving loading a text chunk into a png structure, removing the text, and then adding another text chunk to the structure.
CVE-2009-5063 1 Libpng 1 Libpng 2020-09-09 5.0 MEDIUM N/A
Memory leak in the embedded_profile_len function in pngwutil.c in libpng before 1.2.39beta5 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. NOTE: this is due to an incomplete fix for CVE-2006-7244.
CVE-2019-6129 1 Libpng 1 Libpng 2020-08-24 4.3 MEDIUM 6.5 MEDIUM
** 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-2010-1205 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-2011-2690 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
