| Package | Affected versions | Patched versions |
|---|---|---|
| libpng | ≥ 1.2.0, < 1.2.21< 1.0.29 | 1.2.211.0.29 |
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.
