Multiple security vulnerabilities have been discovered in cURL, an URL transfer
library. These flaws may allow remote attackers to obtain sensitive
information, leak authentication or cookie header data or facilitate a
denial of service attack.

For the stable distribution (bullseye), these problems have been fixed in
version 7.74.0-1.3+deb11u2.

We recommend that you upgrade your curl packages.
