A weakness has been identified in GPAC up to 26.02.0. This affects an unknown part of the file src/utils/base_encoding.c of the component ISOBMFF Parser. Executing a manipulation can lead to highly compressed data. The attack needs to be launched locally. The exploit has been made available to the public and could be used for attacks. This patch is called 297f2d8d1f493d8b241330533cd47f7da758aeb3. A patch should be applied to remediate this issue. The vendor confirms: We added a check on inflate output size, if it surpasses 32 times the input size we stop in error. This value could be adjusted later.
Weakness
The product does not release or incorrectly releases a resource before it is made available for re-use.
Potential Mitigations
- Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
