curl vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 23.10 - Ubuntu 23.04 - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS Summary: Several security issues were fixed in curl. Software Description: - curl: HTTP, HTTPS, and FTP client and client libraries Details: Harry Sintonen discovered that curl incorrectly handled mixed case cookie domains. A remote attacker could possibly use this issue to set cookies that get sent to different and unrelated sites and domains. (CVE-2023-46218) Maksymilian Arciemowicz discovered that curl incorrectly handled long file names when saving HSTS data. This could result in curl losing HSTS data, and subsequent requests to a site would be done without it, contrary to expectations. This issue only affected Ubuntu 23.04 and Ubuntu 23.10. (CVE-2023-46219) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 23.10: curl 8.2.1-1ubuntu3.2 libcurl3-gnutls 8.2.1-1ubuntu3.2 libcurl3-nss 8.2.1-1ubuntu3.2 libcurl4 8.2.1-1ubuntu3.2 Ubuntu 23.04: curl 7.88.1-8ubuntu2.4 libcurl3-gnutls 7.88.1-8ubuntu2.4 libcurl3-nss 7.88.1-8ubuntu2.4 libcurl4 7.88.1-8ubuntu2.4 Ubuntu 22.04 LTS: curl 7.81.0-1ubuntu1.15 libcurl3-gnutls 7.81.0-1ubuntu1.15 libcurl3-nss 7.81.0-1ubuntu1.15 libcurl4 7.81.0-1ubuntu1.15 Ubuntu 20.04 LTS: curl 7.68.0-1ubuntu2.21 libcurl3-gnutls 7.68.0-1ubuntu2.21 libcurl3-nss 7.68.0-1ubuntu2.21 libcurl4 7.68.0-1ubuntu2.21 In general, a standard system update will make all the necessary changes.
