CVSS v3.1
9.8
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
rusqlite versions prior to 0.23.0
Description
An issue was discovered in the rusqlite crate where memory safety can be violated via various means, including use-after-free in the Auxdata API, UnlockNotification, VTab / VTabCursor, sessions.rs, the repr(Rust) type, and rusqlite::trace::log mishandling format strings. Additionally, a data race in the Auxdata API and an issue in create module can also lead to memory safety violations.
Recommendations
For versions prior to 0.23.0, update to version 0.23.0 or later to resolve the issue.
As a temporary workaround, consider disabling the use of the Auxdata API, UnlockNotification, VTab / VTabCursor, sessions.rs, the repr(Rust) type, rusqlite::trace::log, and create module until a patch is available.
Restrict access to the vulnerable components to minimize the risk of exploitation.
Fix
Use of Externally-Controlled Format String
Race Condition
Use After Free
