Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Test your applicationsThere is no fixed version for GPAC4iOS
.
GPAC4iOS is a GPAC4iOS is the libgpac library packaged for iOS as a Pod. It is preconfigured and tested to do a single task: create a MP4 file from a raw H.264 and an audio track.
Affected versions of this package are vulnerable to Heap-based Buffer Overflow.
In order to parse an atom with the “name” FOURCC code, the following function will be used. This function will first take the 64-bit size and truncate it to a 32-bit integer at line 16. After storing the size, the library will then add 1 to it and use it at line 17 to allocate a buffer on the heap. If the 32-bit size is set to UINT_MAX
, this addition will cause an integer overflow resulting in a zero-sized allocation being made. Later at line 18, when the library uses the 32-bit length, the library will read data from the input into the undersized buffer resulting in a large heap-based buffer overflow.
