Summary Summary Microsoft is aware and actively addressing the impact associated with the recent OpenSSL vulnerabilities announced on October 25th 2022, fixed in version 3.0.7. As part of our standard processes, we are rolling out fixes for impacted services. Any customer action that is required will be highlighted in this blog and our associated Security Update Guides (CVE-2022-3786 Security Update Guide and CVE-2022-3602 Security Update Guide).

A vulnerability has been found in Axiomatic Bento4 and classified as problematic. Affected by this vulnerability is an unknown functionality of the component mp4mux. The manipulation leads to memory leak. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-212683.

Organizations should update to the latest encryption (version 3.0.7) as soon as possible, but there's no need for Heartbleed-like panic, security experts say.

In late October two new buffer overflow vulnerabilities, CVE-2022-3602 and CVE-2022-3786, were announced in OpenSSL versions 3.0.0 to 3.0.6. These vulnerabilities can be exploited by sending an X.509 certificate with a specially crafted email address, potentially causing a buffer overflow resulting in a crash or

Ubuntu Security Notice 5710-1 - It was discovered that OpenSSL incorrectly handled certain X.509 Email Addresses. If a certificate authority were tricked into signing a specially-crafted certificate, a remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. The default compiler options for affected releases reduce the vulnerability to a denial of service. It was discovered that OpenSSL incorrectly handled applications creating custom ciphers via the legacy EVP_CIPHER_meth_new function. This issue could cause certain applications that mishandled values to the function to possibly end up with a NULL cipher and messages in plaintext.

A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address to overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash (causing a denial of service) or potentially remote code execution. Many platforms implement stack overflow protections which would mitigate against the risk of remote code execution. The risk may be further mitigated based on stack layout for any given platform/compiler. Pre-announcements of CVE-2022-3602 described this issue as CRITICAL. Further analysis based on some of the mitigating factors described above have led this to be downgraded to HIGH. Users are still encouraged to up...
