CVE-2018-6065 – Google Chromium V8 Integer Overflow Vulnerability

https://notcve.org/view.php?id=CVE-2018-6065

Integer overflow in computing the required allocation size when instantiating a new javascript object in V8 in Google Chrome prior to 65.0.3325.146 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. Desbordamiento de enteros en el cálculo del tamaño de asignación requerido al instanciar un nuevo objeto JavaScript en V8 en Google Chrome en versiones anteriores a la 65.0.3325.146 permitía que un atacante remoto pudiese explotar una corrupción de memoria dinámica (heap) mediante una página HTML manipulada. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Xiaomi Mi6 Browser. 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 handling of the CalculateInstanceSizeHelper function. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. • https://www.exploit-db.com/exploits/44584 https://github.com/b1tg/CVE-2018-6065-exploit http://www.securityfocus.com/bid/103297 https://access.redhat.com/errata/RHSA-2018:0484 https://chromereleases.googleblog.com/2018/03/stable-channel-update-for-desktop.html https://crbug.com/808192 https://www.debian.org/security/2018/dsa-4182 https://www.zerodayinitiative.com/advisories/ZDI-19-367 https://access.redhat.com/security/cve/CVE-2018-6065 https://bugzilla.redhat.com/show_bug&# • CWE-190: Integer Overflow or Wraparound •
