Summary:	The remote host is missing an update for the 'openssl'; package(s) announced via the DSA-4963-1 advisory.
Description:	Summary: The remote host is missing an update for the 'openssl' package(s) announced via the DSA-4963-1 advisory. Vulnerability Insight: Multiple vulnerabilities have been discovered in OpenSSL, a Secure Sockets Layer toolkit. CVE-2021-3711 John Ouyang reported a buffer overflow vulnerability in the SM2 decryption. An attacker able to present SM2 content for decryption to an application can take advantage of this flaw to change application behaviour or cause the application to crash (denial of service). CVE-2021-3712 Ingo Schwarze reported a buffer overrun flaw when processing ASN.1 strings in the X509_aux_print() function, which can result in denial of service. Affected Software/OS: 'openssl' package(s) on Debian Linux. Solution: For the oldstable distribution (buster), these problems have been fixed in version 1.1.1d-0+deb10u7. For the stable distribution (bullseye), these problems have been fixed in version 1.1.1k-1+deb11u1. We recommend that you upgrade your openssl packages.
