USN-6429-1: curl vulnerabilities
11 October 2023
Several security issues were fixed in curl.
Releases
Packages
- 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)
