Description

Redis is an in-memory database that persists on disk. In Redit 7.0 prior to 7.0.12, extracting key names from a command and a list of arguments may, in some cases, trigger a heap overflow and result in reading random heap memory, heap corruption and potentially remote code execution. Several scenarios that may lead to authenticated users executing a specially crafted `COMMAND GETKEYS` or `COMMAND GETKEYSANDFLAGS`and authenticated users who were set with ACL rules that match key names, executing a specially crafted command that refers to a variadic list of key names. The vulnerability is patched in Redis 7.0.12.

• CWE-122Heap-based Buffer OverflowA heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
• CWE-131Incorrect Calculation of Buffer SizeThe product does not correctly calculate the size to be used when allocating a buffer, which could lead to a buffer overflow.
• CWE-787Out-of-bounds WriteThe product writes data past the end, or before the beginning, of the intended buffer.
