Everyone knows WinRAR and has already tested this utility for compressing files. Despite being a constant presence, his name has been back in the spotlight for quite some time now, due to new features coming to Windows 11. This is happening again now, but for much worse reasons. It has a very serious security flaw and needs to be updated.
A serious security vulnerability in WinRAR
Although it is a paid tool and there are free competitors, WinRAR has always been the choice of many users. The reasons are often personal and even with Windows 11 promising support for new files, many have chosen to stick with this suggestion.
With proofs of quality provided in the past, being the logical choice for many, an important question now arises. Is this a safe tool or not? The reason comes from a very serious security flaw discovered by a security investigator from the Zero Day Initiative.
what it was open Is that WinRAR has a flaw that allows an attacker to run other applications on Windows. This is a serious problem, as it can be used to open the door to other attacks and make these systems vulnerable.
The solution is to update this app
The problem stems from the lack of proper validation of the data provided by the user. This can cause memory accesses after the end of the allocated buffer. By forcing a file to open, its severity ends up dropping a few points.
A security investigator reported the flaw found for WinRAR on July 8th. The company tried to solve the problem after that released Version 6.23 on August 2, with this patch and the end of the vulnerability.
So it is necessary to update WinRAR to the latest version, so that the problems are mitigated. With Microsoft testing support for RAR, 7-Zip, and GZ files in Windows 11, the real need for this program is in question.
