For the oldstable distribution (buster), these problems have been fixed in version 0.9.1-1+deb10u1.

For the stable distribution (bullseye), these problems have been fixed in version 0.9.4+dfsg-1+deb11u1.

We recommend that you upgrade your uriparser packages.

For the detailed security status of uriparser please refer to its security tracker page at: [link moved to references]");
