curl vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 ESM
- Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in curl.

Software Description:
- 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 ESM:
curl 7.47.0-1ubuntu2.19+esm4
libcurl3 7.47.0-1ubuntu2.19+esm4
libcurl3-gnutls 7.47.0-1ubuntu2.19+esm4
libcurl3-nss 7.47.0-1ubuntu2.19+esm4

Ubuntu 14.04 ESM:
curl 7.35.0-1ubuntu2.20+esm11
libcurl3 7.35.0-1ubuntu2.20+esm11
libcurl3-gnutls 7.35.0-1ubuntu2.20+esm11
libcurl3-nss 7.35.0-1ubuntu2.20+esm11

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