DATE CVE VULNERABILITY TITLE RISK
2010-06-30 CVE-2010-1205 Classic Buffer Overflow vulnerability in multiple products
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.
9.8
2010-03-03 CVE-2010-0205 Resource Exhaustion vulnerability in multiple products
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.
4.3
2009-06-12 CVE-2009-2042 Information Exposure vulnerability in Libpng
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.

libpng CWE-200
4.3
2009-02-20 CVE-2008-6218 Resource Management Errors vulnerability in Libpng
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.

libpng CWE-399
7.1
2009-01-15 CVE-2008-5907 Remote Security vulnerability in libpng3
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.

2008-09-11 CVE-2008-3964 Off-by-one Error vulnerability in Libpng
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.

libpng CWE-193
4.3
2008-04-14 CVE-2008-1382 Numeric Errors vulnerability in Libpng
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.

7.5
2007-10-08 CVE-2007-5269 Improper Input Validation vulnerability in Libpng
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.

2007-10-08 CVE-2007-5268 Remote Denial of Service vulnerability in Libpng Library
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.

2007-10-08 CVE-2007-5267 Numeric Errors vulnerability in Libpng
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.
