CVE-2010-0205 |
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.

V4.0:(not available) V3.x:(not available) V2.0: 4.3 MEDIUM |
CVE-2009-2042 |
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.

V4.0:(not available) V3.x:(not available) V2.0: 4.3 MEDIUM |
CVE-2009-0040 |
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.

V4.0:(not available) V3.x:(not available) V2.0: 6.8 MEDIUM |
CVE-2008-5907 |
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. Published: January 15, 2009; 12:30:00 PM -0500 |
V4.0:(not available) V3.x:(not available) V2.0: 5.0 MEDIUM |
CVE-2008-3964 |
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.

V4.0:(not available) V3.x:(not available) V2.0: 4.3 MEDIUM |
CVE-2008-1382 |
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. Published: April 14, 2008; 12:05:00 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 7.5 HIGH |
CVE-2007-5266 |
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. Published: October 08, 2007; 5:17:00 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 4.3 MEDIUM |
CVE-2007-5267 |
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. Published: October 08, 2007; 5:17:00 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 4.3 MEDIUM |
CVE-2007-5268 |
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. Published: October 08, 2007; 5:17:00 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 4.3 MEDIUM |
CVE-2007-5269 |
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.
