Package : nss
Version : 2:3.26.2-1.1+deb9u3
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 Debian 9 stretch, this problem has been fixed in version
2:3.26.2-1.1+deb9u3.

We recommend that you upgrade your nss packages.

For the detailed security status of nss please refer to
