libpng png_decompress_chunk() function denial of service
| libpng-pngdecompresschunk-dos (56661) |  Low Risk |
Description:
libpng is vulnerable to a denial of service, caused by an error in the png_decompress_chunk() function. By persuading a victim to open a specially-crafted PNG file containing highly compressed ancillary chunks, a remote attacker could exploit this vulnerability to cause the affected application to hang.
*CVSS:
| Base Score: | 4.3 |
| Access Vector: | Network |
| Access Complexity: | Medium |
| Authentication: | None |
| Confidentiality Impact: | None |
| Integrity Impact: | None |
| Availability Impact: | Partial |
| Temporal Score: | 3.2 |
| Exploitability: | Unproven |
| Remediation Level: | Official-Fix |
| Report Confidence: | Confirmed |
Consequences:

- 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.
