Due to improper error handling in SAP NetWeaver Application Server Java - versions KRNL64NUC 7.22, 7.22EXT, 7.49, KRNL64UC, 7.22, 7.22EXT, 7.49, 7.53, KERNEL 7.22, 7.49, 7.53, an attacker could submit multiple HTTP server requests resulting in errors, such that it consumes the memory buffer. This could result in system shutdown rendering the system unavailable.
Weakness
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
