is public via oss-sec QUIC certificate check bypass with wolfSSL ========================================== Project curl Security Advisory, March 27 2024 - [Permalink](https://curl.se/docs/CVE-2024-2379.html) VULNERABILITY ------------- libcurl skips the certificate verification for a QUIC connection under certain conditions, when built to use wolfSSL. If told to use an unknown/bad cipher or curve, the error path accidentally skips the verification and returns OK, thus ignoring any certificate problems. INFO ---- To trigger, this issue also requires that the used wolfSSL library was built with the `OPENSSL_COMPATIBLE_DEFAULTS` symbol set, which is **not** set for the recommended `configure --enable-curl` builds. The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2024-2379 to this issue. CWE-295: Improper Certificate Validation Severity: Low AFFECTED VERSIONS ----------------- - Affected versions: curl 8.6.0 to and including 8.6.0 - Not affected versions: curl < 8.6.0 and >= 8.7.0 - Introduced-in: https://github.com/curl/curl/commit/5d044ad9480a9f556f4b6a2 libcurl is used by many applications, but not always advertised as such! This flaw is also accessible using the curl command line tool. SOLUTION ------------ Starting in curl 8.7.0, this mistake is fixed. - Fixed-in: https://github.com/curl/curl/commit/aedbbdf18e689a5eee8dc396 RECOMMENDATIONS -------------- A - Upgrade curl to version 8.7.0 B - Apply the patch to your local version C - Avoid using HTTP/3 with curl built to use wolfSSL TIMELINE -------- This issue was reported to the curl project on March 10, 2024. We contacted distros@openwall on March 19, 2024. curl 8.7.0 was released on March 27 2024 around 07:00 UTC, coordinated with the publication of this advisory.
