Overview
An issue was discovered in Bento4 1.6.0-639 where there is excessive memory consumption in the function AP4_Array::EnsureCapacity in Core/Ap4Array.h. This vulnerability allows attackers to cause a denial of service through memory exhaustion (MITRE, NIST).
Technical details
The vulnerability exists in the AP4_Array::EnsureCapacity function within the Core/Ap4Array.h file. When processing certain input files, the function attempts to allocate an excessive amount of memory without proper validation, which can lead to memory exhaustion. The issue has been assigned a CVSS score of 5.5, indicating moderate severity (CISA).
Impact
Successful exploitation of this vulnerability can lead to a denial of service condition through memory exhaustion, potentially causing the application to crash or become unresponsive (MITRE).
Mitigation and workarounds
