Doc Text:
A flaw was found in bit-vec. When an application deserializes data from an untrusted source, the library fails to properly validate the input, leading to undefined behavior during subsequent operations on the bit vector. A remote attacker could exploit this by supplying specially crafted serialized data, potentially causing incorrect execution or an application crash, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-11-13 19:01:52 UTC 
bit-vec is a compact vector of bits. Prior to version 0.10.0, there is undefined behavior if a user performs deserialize from an untrusted source and unsafe get_unchecked. A user of this library may be impacted by incorrect behavior if they perform deserialize from an untrusted source and run operations on the deserialized BitVec. This issue has been patched in version 0.10.0.
