Description

An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. The accesses can subsequently lead to local overwriting of memory in the CmpTraceMgr, whereby the attacker can neither gain the values read internally nor control the values to be written. If invalid memory is accessed, this results in a crash.

• CWE-822Untrusted Pointer DereferenceThe product obtains a value from an untrusted source, converts this value to a pointer, and dereferences the resulting pointer.
• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
