A vulnerability classified as problematic has been found in FFmpeg up to 6e26f57f672b05e7b8b052007a83aef99dc81ccb. This affects the function audio_element_obu of the file libavformat/iamf_parse.c of the component IAMF File Handler. The manipulation of the argument num_parameters leads to memory leak. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of the patch is 0526535cd58444dd264e810b2f3348b4d96cff3b. It is recommended to apply a patch to fix this issue.
Weakness
The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory.
Potential Mitigations
- Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
- For example, glibc in Linux provides protection against free of invalid pointers.
- When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
- To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
