USN-6718-3: curl vulnerabilities

Releases

• Ubuntu 24.04 LTS

Packages

• 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

• 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.
