Service interruption via misaligned fixed-size allocator write
Published Aug 22, 2023 · Updated Oct 3, 2024
Out-of-bounds write in Crypto++ 8.4 and earlier allows remote attackers to interrupt service through a misaligned fixed-size allocation. FixedSizeAllocatorWithCleanup returns a pointer outside its embedded array when the array lacks 16-byte alignment, corrupting stack or heap memory. Reachability depends on a consuming application instantiating the affected template under that alignment condition; the documented consequence is memory corruption and a possible crash.
