CVE-2011-0408 1 Libpng 1 Libpng 2025-04-11 6.8 MEDIUM N/A
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 png_do_expand_palette function, the png_do_rgb_to_gray function, and an integer underflow. NOTE: some of these details are obtained from third party information.
CVE-2011-2691 3 Debian, Fedoraproject, Libpng 3 Debian Linux, Fedora, Libpng 2025-04-11 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-2011-3045 6 Debian, Fedoraproject, Google and 3 more 13 Debian Linux, Fedora, Chrome and 10 more 2025-04-11 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-2010-0205 7 Apple, Canonical, Debian and 4 more 7 Mac Os X, Ubuntu Linux, Debian Linux and 4 more 2025-04-11 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 2025-04-11 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-2010-2249 8 Apple, Canonical, Debian and 5 more 12 Iphone Os, Itunes, Safari and 9 more 2025-04-11 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-2007-5266 1 Libpng 1 Libpng 2025-04-09 4.3 MEDIUM N/A
Off-by-one error in ICC profile chunk handling in the png_set_iCCP function in pngset.c in libpng before 1.0.29 beta1 and 1.2.x before 1.2.21 beta1 allows remote attackers to cause a denial of service (crash) via a crafted PNG image that prevents a name field from being NULL terminated.
CVE-2007-5267 1 Libpng 1 Libpng 2025-04-09 4.3 MEDIUM N/A
Off-by-one error in ICC profile chunk handling in the png_set_iCCP function in pngset.c in libpng before 1.2.22 beta1 allows remote attackers to cause a denial of service (crash) via a crafted PNG image, due to an incorrect fix for CVE-2007-5266.
CVE-2008-5907 2 Debian, Libpng 2 Debian Linux, Libpng 2025-04-09 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-2007-5268 2 Canonical, Libpng 2 Ubuntu Linux, Libpng 2025-04-09 4.3 MEDIUM N/A
pngrtran.c in libpng before 1.0.29 and 1.2.x before 1.2.21 use (1) logical instead of bitwise operations and (2) incorrect comparisons, which might allow remote attackers to cause a denial of service (crash) via a crafted PNG image.
CVE-2009-0040 6 Apple, Debian, Fedoraproject and 3 more 9 Iphone Os, Mac Os X, Debian Linux and 6 more 2025-04-09 6.8 MEDIUM N/A
The PNG reference library (aka libpng) before 1.0.43, and 1.2.x before 1.2.35, as used in pngcrush and other applications, allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file that triggers a free of an uninitialized pointer in (1) the png_read_png function, (2) pCAL chunk handling, or (3) setup of 16-bit gamma tables.
CVE-2008-6218 1 Libpng 1 Libpng 2025-04-09 7.1 HIGH N/A
Memory leak in the png_handle_tEXt function in pngrutil.c in libpng before 1.2.33 rc02 and 1.4.0 beta36 allows context-dependent attackers to cause a denial of service (memory exhaustion) via a crafted PNG file.
CVE-2008-1382 1 Libpng 1 Libpng 2025-04-09 7.5 HIGH N/A
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.
CVE-2007-5269 1 Libpng 1 Libpng 2025-04-09 5.0 MEDIUM N/A
Certain chunk handlers in libpng before 1.0.29 and 1.2.x before 1.2.21 allow remote attackers to cause a denial of service (crash) via crafted (1) pCAL (png_handle_pCAL), (2) sCAL (png_handle_sCAL), (3) tEXt (png_push_read_tEXt), (4) iTXt (png_handle_iTXt), and (5) ztXT (png_handle_ztXt) chunking in PNG images, which trigger out-of-bounds read operations.
CVE-2008-3964 1 Libpng 1 Libpng 2025-04-09 4.3 MEDIUM N/A
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-2009-2042 1 Libpng 1 Libpng 2025-04-09 4.3 MEDIUM N/A
libpng before 1.2.37 does not properly parse 1-bit interlaced images with width values that are not divisible by 8, which causes libpng to include uninitialized bits in certain rows of a PNG file and might allow remote attackers to read portions of sensitive memory via "out-of-bounds pixels" in the file.
CVE-2004-0421 4 Libpng, Openpkg, Redhat and 1 more 6 Libpng, Openpkg, Enterprise Linux and 3 more 2025-04-03 5.0 MEDIUM N/A
The Portable Network Graphics library (libpng) 1.0.15 and earlier allows attackers to cause a denial of service (crash) via a malformed PNG image file that triggers an error that causes an out-of-bounds read when creating the error message.
CVE-2021-4214 3 Debian, Libpng, Netapp 3 Debian Linux, Libpng, Ontap Select Deploy Administration Utility 2024-11-21 N/A 5.5 MEDIUM
A heap overflow flaw was found in libpngs' pngimage.c program. This flaw allows an attacker with local network access to pass a specially crafted PNG file to the pngimage utility, causing an application to crash, leading to a denial of service.
CVE-2019-7317 11 Canonical, Debian, Hp and 8 more 33 Ubuntu Linux, Debian Linux, Xp7 Command View and 30 more 2024-11-21 2.6 LOW 5.3 MEDIUM
png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute.
CVE-2019-6129 1 Libpng 1 Libpng 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
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.
