Netpbm through 11.16.00 Heap Out-of-Bounds Read via rasttopnm Colormap

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Netpbm through 11.16.00 contains a heap out-of-bounds read vulnerability in rasttopnm that allows attackers to read heap memory by supplying Sun rasterfiles with short colormaps. Attackers can craft colormapped rasterfiles with pixel bytes exceeding the palette length to leak up to 255 adjacent heap bytes into the PNM output or crash the program.
