CVSS: 8.8EPSS: 96%CPEs: 4EXPL: 1CVE-2021-21220 – Google Chromium V8 Improper Input Validation Vulnerability
https://notcve.org/view.php?id=CVE-2021-21220
Insufficient validation of untrusted input in V8 in Google Chrome prior to 89.0.4389.128 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. Una comprobación insuficiente de una entrada no confiable en V8 en Google Chrome versiones anteriores a e 89.0.4389.128, permitió a un atacante remoto explotar potencialmente una corrupción de la pila por medio de una página HTML diseñada This vulnerability allows remote attackers to execute arbitrary code on affected installations of Google Chromium. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the implementation of the XOR operation when executed within JIT compiled code. By performing actions in JavaScript, an attacker can trigger a memory access past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process. • https://github.com/security-dbg/CVE-2021-21220 http://packetstormsecurity.com/files/162437/Google-Chrome-XOR-Typer-Out-Of-Bounds-Access-Remote-Code-Execution.html http://packetstormsecurity.com/files/176210/Chrome-V8-JIT-XOR-Arbitrary-Code-Execution.html https://chromereleases.googleblog.com/2021/04/stable-channel-update-for-desktop.html https://crbug.com/1196683 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EAJ42L4JFPBJATCZ7MOZQTUDGV4OEHHG https://lists.fedoraproject.org/ • CWE-787: Out-of-bounds Write •
