Description

Jay Satiro discovered that curl incorrectly handled hostnames when using a SOCKS5 proxy. In environments where curl is configured to use a SOCKS5 proxy, a remote attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 23.04. (CVE-2023-38545) It was discovered that curl incorrectly handled cookies when an application duplicated certain handles. A local attacker could possibly create a cookie file and inject arbitrary cookies into subsequent connections. (CVE-2023-38546) Update Instructions: Run sudo pro fix USN-6429-1 to fix the vulnerability. The problem can be corrected by updating your system to the following package versions: libcurl4-gnutls-dev – 7.68.0-1ubuntu2.20 libcurl4-openssl-dev – 7.68.0-1ubuntu2.20 libcurl3-gnutls – 7.68.0-1ubuntu2.20 libcurl4-doc – 7.68.0-1ubuntu2.20 libcurl3-nss – 7.68.0-1ubuntu2.20 libcurl4-nss-dev – 7.68.0-1ubuntu2.20 libcurl4 – 7.68.0-1ubuntu2.20 curl – 7.68.0-1ubuntu2.20 No subscription required
