What to do
AI-suggested
Fixed package versions have been released by Ubuntu and Red Hat. Users should apply the security updates provided for their respective distributions and versions. For Ubuntu, standard system updates or Ubuntu Pro fixes are available for all affected LTS releases. For Red Hat Hardened Images, update to curl-8.21.0-0.1.hum1 and related libcurl packages. No additional mitigation steps are indicated beyond applying these official patches.
Description
Multiple security vulnerabilities have been identified in the cURL client software affecting various Ubuntu LTS releases and Red Hat Hardened Images. These include issues with connection reuse during STARTTLS upgrades, incorrect connection reuse for Negotiate authentication, improper cookie parsing, double-free vulnerabilities, password selection errors, proxy authentication state leakage, use-after-free conditions, early data transmission before certificate verification, and SSH host key mismatches. The vulnerabilities could allow remote attackers to cause denial of service, execute arbitrary code, access unauthorized resources, or obtain sensitive information. Fixes have been released for affected Ubuntu and Red Hat packages.
