Security Updates for Internet Explorer (October 2019)

High Nessus Plugin ID 129728

Synopsis

The Internet Explorer installation on the remote host is affected by multiple vulnerabilities.

Description

The Internet Explorer installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists in the way that the VBScript engine handles objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2019-1238)

- A spoofing vulnerability exists when Microsoft Browsers improperly handle browser cookies. An attacker who successfully exploited this vulnerability could trick a browser into overwriting a secure cookie with an insecure cookie. The insecure cookie could serve as a pivot to chain an attack with other vulnerabilities in web services. (CVE-2019-1357)

- A spoofing vulnerability exists when Microsoft Browsers does not properly parse HTTP content. An attacker who successfully exploited this vulnerability could impersonate a user request by crafting HTTP queries. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. (CVE-2019-0608)

- A remote code execution vulnerability exists when Internet Explorer improperly accesses objects in memory.
The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2019-1371)
