There is a use after free vulnerability in Taurus-AL00A versions 10.0.0.1(C00E1R1P1). A module does not deal with specific message properly, which makes a function refer to memory after it has been freed. Attackers can exploit this vulnerability by running a crafted application with common privilege. This would compromise normal service.

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
