Companies that use OpenSSL in their products have started releasing security advisories to inform customers about the impact of two recently patched vulnerabilities.

Updates announced by the OpenSSL Project on August 24 patched CVE-2021-3711, a high-severity buffer overflow, and CVE-2021-3712, a medium-severity flaw that can be exploited for denial-of-service (DoS) attacks, and possibly for the disclosure of private memory contents.

The high-severity vulnerability, patched with the release of OpenSSL 1.1.1l, can allow an attacker to change an application’s behavior or cause it to crash.

Several major organizations whose products rely on OpenSSL have released security advisories, including Linux distributions such as Red Hat, Ubuntu, SUSE, Debian, and Alpine Linux.

Network-attached storage (NAS) appliance maker Synology has informed customers that the OpenSSL vulnerabilities impact its Synology DiskStation Manager (DSM), Synology Router Manager (SRM), VPN Plus Server, and VPN Server products.

The company has assigned “important” and “moderate” severity ratings to these vulnerabilities and says it’s working on patches.

QNAP has also released an advisory, telling customers that it’s “thoroughly investigating the case” and it “will release security updates and provide further information as soon as possible.”

Other major companies, such as Cisco and Broadcom, are also expected to release advisories describing the impact of the latest OpenSSL vulnerabilities on their products.
