CVE-2020-24588 8 Arista, Cisco, Debian and 5 more 350 C-100, C-100 Firmware, C-110 and 347 more 2024-11-21 2.9 LOW 3.5 LOW
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets.

Windows Spoofing Vulnerability
CVE-2020-1598 1 Microsoft 8 Windows 10, Windows 7, Windows 8.1 and 5 more 2024-11-21 4.6 MEDIUM 6.1 MEDIUM
<p>An elevation of privilege vulnerability exists when the Windows Universal Plug and Play (UPnP) service improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.</p> <p>To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted script or application.</p> <p>The update addresses the vulnerability by correcting how the Windows UPnP service handles objects in memory.</p>
CVE-2020-1596 1 Microsoft 8 Windows 10, Windows 7, Windows 8.1 and 5 more 2024-11-21 2.9 LOW 5.4 MEDIUM
<p>A information disclosure vulnerability exists when TLS components use weak hash algorithms. An attacker who successfully exploited this vulnerability could obtain information to further compromise a users's encrypted transmission channel.</p> <p>To exploit the vulnerability, an attacker would have to conduct a man-in-the-middle attack.</p> <p>The update addresses the vulnerability by correcting how TLS components use hash algorithms.</p>
CVE-2020-1593 1 Microsoft 8 Windows 10, Windows 7, Windows 8.1 and 5 more 2024-11-21 6.8 MEDIUM 7.6 HIGH
<p>A remote code execution vulnerability exists when Windows Media Audio Decoder improperly handles objects. An attacker who successfully exploited the vulnerability could take control of an affected system.</p> <p>There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit a malicious webpage.</p> <p>The security update addresses the vulnerability by correcting how Windows Media Audio Decoder handles objects.</p>
CVE-2020-1589 1 Microsoft 8 Windows 10, Windows 7, Windows 8.1 and 5 more 2024-11-21 2.1 LOW 4.4 MEDIUM
<p>An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.</p> <p>To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.</p> <p>The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory.</p>
CVE-2020-1587 1 Microsoft 8 Windows 10, Windows 7, Windows 8.1 and 5 more 2024-11-21 7.2 HIGH 7.8 HIGH
An elevation of privilege vulnerability exists when the Windows Ancillary Function Driver for WinSock improperly handles memory. To exploit this vulnerability, an attacker would first have to gain execution on the victim system. An attacker could then run a specially crafted application to elevate privileges. The security update addresses the vulnerability by correcting how the Windows Ancillary Function Driver for WinSock handles memory.
CVE-2020-1584 1 Microsoft 8 Windows 10, Windows 7, Windows 8.1 and 5 more 2024-11-21 7.2 HIGH 7.8 HIGH
An elevation of privilege vulnerability exists in the way that the dnsrslvr.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. To exploit the vulnerability, a locally authenticated attacker could run a specially crafted application. The security update addresses the vulnerability by ensuring the dnsrslvr.dll properly handles objects in memory.
CVE-2020-1579 1 Microsoft 8 Windows 10, Windows 7, Windows 8.1 and 5 more 2024-11-21 7.2 HIGH 7.8 HIGH
An elevation of privilege vulnerability exists when the Windows Function Discovery SSDP Provider improperly handles memory. To exploit this vulnerability, an attacker would first have to gain execution on the victim system. An attacker could then run a specially crafted application to elevate privileges. The security update addresses the vulnerability by correcting how the Windows Function Discovery SSDP Provider handles memory.
CVE-2020-1577 1 Microsoft 8 Windows 10, Windows 7, Windows 8.1 and 5 more 2024-11-21 4.3 MEDIUM 7.8 HIGH
An information disclosure vulnerability exists when DirectWrite improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how DirectWrite handles objects in memory.
