News regarding fixed curl vulnerabilities across multiple Ubuntu versions. Keep your system safe by updating to the newest releases.
Several security issues were fixed in curl.

Summary

Several security issues were fixed in curl.

Software Description:

- curl: HTTP, HTTPS, and FTP client and client libraries

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)
