        Microsoft Windows Security Update.
Microsoft on Tuesday released fixes for 58 newly discovered security flaws spanning as many as 11 products and services as part of its final Patch Tuesday of 2020, effectively bringing their CVE total to 1,250 for the year.

Of these 58 patches, nine are rated as Critical, 46 are rated as Important, and three are rated Moderate in severity.

The December security release addresses issues in Microsoft Windows, Edge browser, ChakraCore, Microsoft Office, Exchange Server, Azure DevOps, Microsoft Dynamics, Visual Studio, Azure SDK, and Azure Sphere.

Fortunately, none of these flaws this month have been reported as publicly known or being actively exploited in the wild.

The fixes for December concern a number of remote code execution (RCE) flaws in Microsoft Exchange (CVE-2020-17132), SharePoint (CVE-2020-17118 and CVE-2020-17121), Excel (CVE-2020-17123), and Hyper-V virtualization software (CVE-2020-17095), as well as a patch for a security feature bypass in Kerberos (CVE-2020-16996), and a number of privilege escalation flaws in Windows Backup Engine and Windows Cloud Files Mini Filter Driver.

CVE-2020-17095 also carries the highest CVSS score of 8.5 among all vulnerabilities addressed in this month's release.

"To exploit this vulnerability, an attacker could run a specially crafted application on a Hyper-V guest that could cause the Hyper-V host operating system to execute arbitrary code when it fails to properly validate vSMB packet data," Microsoft noted.

Additionally included as part of this month's release is an advisory for a DNS cache poisoning vulnerability (CVE-2020-25705) discovered by security researchers from Tsinghua University and the University of California last month.

Dubbed a Side-channel AttackeD DNS attack (or SAD DNS attack), the flaw could enable an attacker to spoof the DNS packet, which can be cached by the DNS Forwarder or the DNS Resolver, thereby re-enabling DNS cache poisoning attacks.

To mitigate the risk, Microsoft recommends a Registry workaround that involves changing the maximum UDP packet size to 1,221 bytes (4C5 Hexadecimal).

"For responses larger than 4C5 or 1221, the DNS resolver would now switch to TCP," the Windows maker stated in its advisory.

Since the attack relies on sending spoofed UDP (User Datagram Protocol) messages to defeat source port randomization for DNS requests, implementing the tweak will cause larger DNS queries to switch to TCP, thus mitigating the flaw.

It's highly advised that Windows users and system administrators apply the latest security patches to resolve the threats associated with these issues.

To install the latest security updates, Windows users can head to Start > Settings > Update & Security > Windows Update, or by selecting Check for Windows updates.

UGANDA ELECTORAL COMMISSION TO ELIMINATE NATIONAL IDENTIFICATION CARDS (IDs) FOR 2021 GENERAL ELECTIONS.

By Editor
The elimination of using National IDs (Ndagamuntu) for the 2021 elections should not have come as a surprise. One would be very NAIVE to think that Bobi Wine has not prepared for this in his Business Plan under the RISK section. It is public knowledge that our EC is not independent.  It is also public knowledge that Military Dictator Yoweri Museveni will never lose an election. What stunned us this morning is when we noticed that on social media, people were mocking Bobi with his "get your Ndagamuntu".  We are on record for saying to all Our readers that the National ID is like Apartheid in South Africa. Students of History would know how those IDs were being used to arrest people, deny them jobs, deny them basic services. Consequently, Bobi was not wrong and will never be wrong on the Ndagamuntu. Except the ones attacking him and mocking him forget that in Uganda, now, no National ID (Ndagamuntu), no service.  If you have not been denied registering your child i...

        President Museveni at the passout of police officers in Masindi Friday https://www.facebook.com/1829407613953796 President Museveni has praised his Special Forces Command [SFC] guards for properly and legally beating National Unity Platform [NUP] presidential flagbearer, Robert Kyagulanyi aka Bobi Wine. “The other day, there was a fracas in West Nile where our young friend Bobi Wine was fighting security people,” Museveni said Friday while passing out police recruits at Kabalye Training School in Masindi district. “I think they beat him a bit and then they came and said a Member of Parliament has been beaten. I said let me study and see how he was beaten. I found the man had been beaten in the right way,” Museveni explained. “This was because…I think this was SFC people who are not police-minded. They are used to doing other things. But somehow they managed to act properly, I was surprised.” When they [SFC] went where this young man was in the room, he had ca...

Here is Why Our Utterances For Praying Jesus And God To Come Liberate Ugandans, May Be Misplaced. This Phrase is like inform of a Letter To Some Categorized Section Of Ugandans.

Last week of March, a friend told me to pray for Uganda.  I told him that he was an Idiot and we have prayed for too long and we are still hungry and sick and Jesus is not coming soon to liberate us. He then ignored the STUPID and sent me a picture we all now know.  It got me totally messed up.  This guy was telling me to pray then sends a picture of men bowing down in blood.  He might have meant guns but I blocked him because his utterances of praying for Uganda were misplaced. I unblocked him 3 weeks later and asked him about praying and assassinations.  His reply "eithrr prayers or guns or both". I hate violence with a passion.  So he is now blocked in like FOREVER. Do you feel safe?  Do not feel safe. Uganda regim...
