Published: 8 October 2007
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.
Notes
| Author | Note |
|---|---|
| jdstrand | DoS on many systems theoretically not vulnerable because the affected code uses png_strncpy with bad args, but our versions use png_strcpy. TODO: get reproducer and/or verify png_strcpy usage upstream did not provide reproducer. code not in existing versions fully fixed in 1.2.22 |
