GHSA-4FCV-W3QC-PPGG

Vulnerability from github – Published: 2025-04-04 20:31 – Updated: 2025-04-04 20:31
VLAI?
Summary
rust-openssl Use-After-Free in `Md::fetch` and `Cipher::fetch`
Details

When a Some(...) value was passed to the properties argument of either of these functions, a use-after-free would result.

In practice this would nearly always result in OpenSSL treating the properties as an empty string (due to CString::drop's behavior).

The maintainers thank quitbug for reporting this vulnerability to us.

Severity ?
6.3 (Medium)
CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N
