GHSA-5PHC-849H-VCXG `Read` on uninitialized buffer can cause UB (impl of `ReadKVExt`)
Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation. Arbitrary Read implementations can read from the uninitialized buffer memory exposure and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory...
GHSA-C6PX-4GRW-HRJR 'Read' on uninitialized memory may cause UB
Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation. The crate currently contains 4 occurrences of such cases. Arbitrary Read implementations can read from the uninitialized buffer memory exposure and also can return incorrect number of bytes...
