Summary

LodePNG through 20261006 contains a heap out-of-bounds read vulnerability in lodepng::getFilterTypesInterlaced() in lodepng_util.cpp that lacks bounds checks on decompressed IDAT data. Attackers can supply a crafted interlaced PNG declaring a raster larger than its IDAT stream to disclose adjacent heap memory or crash applications.

Risk Assessment

An attacker can disclose sensitive heap memory data or crash an application processing a malicious PNG file.

Recommendation

Update the LodePNG library to a version later than 20261006 that includes the fix for this vulnerability.
