Loading vulnerability details...
Affected versions of this crate did not check that the input slice passed to "webp::Encoder::encode() is large enough for the specified image dimensions.
If the input slice is too short, the library will read out of bounds of the buffer and encode other memory contents as an image, resulting in memory exposure or a segmentation fault.
The flaw was corrected in pull request #44 by always validating the input buffer size when constructing the encoder.

This medium-severity vulnerability could be exploited under certain conditions to compromise security controls or access sensitive information. Should be addressed in a timely manner.
Apply security patches to version 0.3.1 immediately
Isolate affected systems from untrusted networks until patching is complete
