![]() Based on our current understanding of the vulnerabilities, CVE-2022-3786 and CVE-2022-3602, patched in OpenSSL 3.0.7, GreyNoise is unlikely to observe opportunistic mass exploitation in the wild. Fixed in OpenSSL 3.0.7 (Affected 3.0.0,3.0.1,3.0.2,3.0.3,3.0.4,3.0.5,3.0.6). Vulnerability OpenSSL v3 (are still encouraged to upgrade to a new version as soon as possible. low: core: Possible buffer overflow with very large or unlimited LimitXMLRequestBody (CVE-2022-22721) If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. This buffer overflow could result in a crash (causing a denial of service) or potentially remote code execution,' allowing them to take control of an affected system. Further analysis based on some of the mitigating factors described above have led this to be downgraded to HIGH. According to OpenSSL, a cyber threat actor leveraging CVE-2022-3786, 'can craft a malicious email address to overflow four attacker-controlled bytes on the stack. ![]() Pre-announcements of CVE-2022-3602 described this issue as CRITICAL. The risk may be further mitigated based on stack layout for any given platform/compiler. OpenSSL through 1.0.2h incorrectly uses pointer arithmetic for heap-buffer boundary checks, which might allow remote attackers to cause a denial of service (integer overflow and application crash) or possibly have unspecified other impact by leveraging unexpected malloc behavior, related to s3srvr.c, sslsess.c, and t1lib.c. CVE-2023-5217: Heap buffer overflow in vp8 encoding in libvpx in Google Chrome prior to 1.132 and libvpx 1.13.1 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. Many platforms implement stack overflow protections which would mitigate against the risk of remote code execution. Heap-based Buffer Overflow in GitHub repository vim/vim prior to. This buffer overflow could result in a crash (causing a denial of service) or potentially remote code execution. An attacker can craft a malicious email address to overflow four attacker-controlled bytes on the stack. 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. A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Multiple buffer overflows in crypto/srp/srplib.c in the SRP implementation in OpenSSL 1.0.1 before 1.0.1i allow remote attackers to cause a denial of. ![]()
