Description Vipul Nair 2023-08-29 12:37:49 UTC 
Crypto++ through 8.4 contains a timing side channel in ECDSA signature generation. Function FixedSizeAllocatorWithCleanup could write to memory outside of the allocation if the allocated memory was not 16-byte aligned. NOTE: this issue exists because the CVE-2019-14318 fix was intentionally removed for functionality reasons.
