Summary
curl vulnerabilities
Details

Harry Sintonen discovered that curl incorrectly handled HSTS support when multiple URLs are requested serially. A remote attacker could possibly use this issue to cause curl to use unencrypted connections. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2023-23914)

Harry Sintonen discovered that curl incorrectly handled HSTS support when multiple URLs are requested in parallel. A remote attacker could possibly use this issue to cause curl to use unencrypted connections. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2023-23915)

Patrick Monnerat discovered that curl incorrectly handled memory when processing requests with multi-header compression. A remote attacker could possibly use this issue to cause curl to consume resources, leading to a denial of service. (CVE-2023-23916)
