Critical WhatsApp Bugs Could Have Let Attackers Hack Devices Remotely.




WhatsApp has released security updates to address two flaws in its messaging app for Android and iOS that could lead to remote code execution on vulnerable devices.


One of them concerns CVE-2022-36934 (CVSS score: 9.8), a critical integer overflow vulnerability in WhatsApp that results in the execution of arbitrary code simply by establishing a video call.


The issue impacts the WhatsApp and WhatsApp Business for Android and iOS prior to versions 2.22.16.12.


Also patched by the Meta-owned messaging platform is an integer underflow bug, which refers to an opposite category of errors that occur when the result of an operation is too small for storing the value within the allocated memory space.


The high-severity issue, given the CVE identifier CVE-2022-27492 (CVSS score: 7.8), affects WhatsApp for Android prior to versions 2.22.16.2 and WhatsApp for iOS version 2.22.15.9, and could be triggered upon receiving a specially crafted video file.


Exploiting integer overflows and underflows are a stepping stone towards inducing undesirable behavior, causing unexpected crashes, memory corruption, and code execution.


WhatsApp did not share more specifics on the vulnerabilities, but cybersecurity firm Malwarebytes said that they reside in two components called Video Call Handler and Video File Handler, which could permit an attacker to seize control of the app.


A spokesperson for WhatsApp told The Hacker News that "we discovered [the flaws] ourselves and there was no evidence of exploitation."


Vulnerabilities on WhatsApp can be a lucrative attack vector for threat actors looking to plant malicious software on compromised devices. In 2019, an audio calling flaw was exploited by the Israeli spyware maker NSO Group to inject the Pegasus spyware.

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

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...

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...

Okello lost his wife 20 years ago and decided to only focus on their Mateo, Yona and Yosefu. 20 years later, Okello had 7 acres of land, a successful poultry business, and sinotrucks for hire. Early this year, Okello got a call telling him that one of his trucks knocked a boda boda. Okello decided to rush to see if he could sort it out before police became involved. Unfortunately, he never made it, as he was entering the main road, another trailer rammed into him and killed him instantly.   After Okello had been laid to rest, his sons sat down and divided the property amongst themselves. However, of late, Yosefu the last born has started complaining that he was cheated, and he wants to be given something else because most of the chicken in the chicken business died of a fever.   Can ...
