Details

USN-6429-1 fixed vulnerabilities in curl. This update provides the
corresponding updates for Ubuntu 23.10.

Original advisory details:

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)
