Ronald Crane discovered that missing input saniting in the apr_encode
functions of apr, the Apache Portable Runtime library, may result in
denial of service or potentially the execution of arbitrary code.

For the stable distribution (bullseye), this problem has been fixed in

We recommend that you upgrade your apr packages.
