bep/imagemeta allows a potentially large memory allocation in PNG and WebP parsing
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|

Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
The buffer created for parsing metadata for PNG and WebP images was only bounded by their input data type, which could lead to potentially large memory allocation, and unreasonably high for image metadata. Before `v0.11.0`, If you didn't trust the input images, this could be abused to construct denial-of-service attacks.
### Patches
`v0.11.0` added a 10 MB upper limit.
