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

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

- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in curl.

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

Details:

USN-6718-1 fixed vulnerabilities in curl. This update provides the
corresponding updates for Ubuntu 24.04 LTS.

Original advisory details:

  Dan Fandrich discovered that curl would incorrectly use the default set of
  protocols when a parameter option disabled all protocols without adding
  any, contrary to expectations. This issue only affected Ubuntu 23.10.
  (CVE-2024-2004)
   It was discovered that curl incorrectly handled memory when limiting the
  amount of headers when HTTP/2 server push is allowed. A remote attacker
  could possibly use this issue to cause curl to consume resources, leading
  to a denial of service. (CVE-2024-2398)

Update instructions:

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

Ubuntu 24.04 LTS
   curl                            8.5.0-2ubuntu10.1
   libcurl3t64-gnutls              8.5.0-2ubuntu10.1
   libcurl4t64                     8.5.0-2ubuntu10.1

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