curl vulnerability

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

– Ubuntu 23.04


curl could be made to consume resources if it received specially crafted
network traffic.

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


It was discovered that curl incorrectly handled certain large headers. A
remote attacker could possibly use this issue to cause curl to consume
resources, resulting in a denial of service.

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

Ubuntu 23.04:
curl 7.88.1-8ubuntu2.2
libcurl3-gnutls 7.88.1-8ubuntu2.2
