Package        : nss
CVE ID         : CVE-2021-43527

Tavis Ormandy discovered that nss, the Mozilla Network Security Service
library, is prone to a heap overflow flaw when verifying DSA or RSA-PPS
signatures, which could result in denial of service or potentially the
execution of arbitrary code.

For the oldstable distribution (buster), this problem has been fixed
in version 2:3.42.1-1+deb10u4.

For the stable distribution (bullseye), this problem has been fixed in
version 2:3.61-1+deb11u1.

We recommend that you upgrade your nss packages.

For the detailed security status of nss please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/nss
