Description

Hiroki Kurosawa discovered that curl incorrectly handled HSTS support when certain hostnames included IDN characters. 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-2022-43551) It was discovered that curl incorrectly handled denials when using HTTP proxies. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2022-43552) Update Instructions: Run sudo pro fix USN-5788-1 to fix the vulnerability. The problem can be corrected by updating your system to the following package versions: libcurl4-gnutls-dev – 7.58.0-2ubuntu3.22 libcurl4-openssl-dev – 7.58.0-2ubuntu3.22 libcurl3-gnutls – 7.58.0-2ubuntu3.22 libcurl4-doc – 7.58.0-2ubuntu3.22 libcurl3-nss – 7.58.0-2ubuntu3.22 libcurl4-nss-dev – 7.58.0-2ubuntu3.22 libcurl4 – 7.58.0-2ubuntu3.22 curl – 7.58.0-2ubuntu3.22 No subscription required
