An attacker can take advantage of this flaw for denial of service or potentially the execution of arbitrary code.

For the stable distribution (buster), this problem has been fixed in version 1.42.4-7~deb10u1.

We recommend that you upgrade your pango1.0 packages.

For the detailed security status of pango1.0 please refer to its security tracker page at: [link moved to references]");
