USN-5499-1: curl vulnerabilities

1 July 2022

Several security issues were fixed in curl.

Releases

Packages

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

Details

Florian Kohnhuser discovered that curl incorrectly handled returning a
TLS server’s certificate chain details. A remote attacker could possibly
use this issue to cause curl to stop responding, resulting in a denial of
service. (CVE-2022-27781)

Harry Sintonen discovered that curl incorrectly handled certain FTP-KRB
messages. An attacker could possibly use this to perform a
machine-in-the-middle attack. (CVE-2022-32208)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.04
Ubuntu 14.04

In general, a standard system update will make all the necessary changes.
