Multiple Vulnerabilities in Google Chrome Could Allow for Arbitrary Code Execution

Read Time:32 Second

Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Google Chrome is a web browser used to access the Internet. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

USN-5504-1: Firefox vulnerabilities

Read Time:1 Minute, 4 Second

Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, spoof the
browser UI, bypass CSP restrictions, bypass sandboxed iframe restrictions,
obtain sensitive information, bypass the HTML sanitizer, or execute
arbitrary code. (CVE-2022-2200, CVE-2022-34468, CVE-2022-34470,
CVE-2022-34473, CVE-2022-34474, CVE-2022-34475, CVE-2022-34476,
CVE-2022-34477, CVE-2022-34479, CVE-2022-34480, CVE-2022-34481,
CVE-2022-34484, CVE-2022-34485)

It was discovered that Firefox could be made to save an image with an
executable extension in the filename when dragging and dropping an image
in some circumstances. If a user were tricked into dragging and dropping
a specially crafted image, an attacker could potentially exploit this to
trick the user into executing arbitrary code. (CVE-2022-34482,
CVE-2022-34483)

It was discovered that a compromised server could trick Firefox into an
addon downgrade in some circumstances. An attacker could potentially
exploit this to trick the browser into downgrading an addon to a prior
version. (CVE-2022-34471)

It was discovered that an unavailable PAC file caused OCSP requests to
be blocked, resulting in incorrect error pages being displayed.
