In most cases, the best thing to do is to keep our computer updated with regard to all its software. Here both the operating system and the different applications that we have installed come into play, all of which will help us to work with a more secure PC.
In this case, we want to focus on extremely popular software that has been used over the last decades and that you may have installed on your computer. This is a well-known file compressor that now has a serious vulnerability, so it should be updated as soon as possible. Specifically, we are referring to the well-known WinRAR that at this moment could be endangering our computer and all the data stored on it.
That is precisely why its top managers recommend that we install the latest file compressor update as soon as possible. The main reason for all this is that they have discovered a serious remote code execution vulnerability that puts our PC at risk. Initially, this vulnerability that we are talking about has been identified as CVE-2023-40477, and it is a security flaw that was discovered in June.
To give us a better idea of ​​what we are talking about, it is worth mentioning that this bug allows attackers to execute malicious code by opening a simple file in RAR format. Since its discovery, the developers of the program have been working on solving the bug and they have finally succeeded. Now we can affirm that two months later, the problem has been solved. Of course, for everything to go well, software users will have to make sure they have the latest update installed. All this in order to guarantee adequate protection for our equipment.
Update WinRAR as soon as possible
Here we are referring to a serious flaw discovered by a security researcher about 2 months ago. It is important that we bear in mind that the seriousness of this is due to the fact that just by opening a specially created RAR file, an attempt is made to trick the victim into executing arbitrary code that could cause enormous damage to the computer.
As previously reported, this is a vulnerability that allows remote attackers to execute arbitrary code on affected systems. In principle, it requires user interaction to exploit this vulnerability, since the target must visit a malicious page or open a modified file.
Being a bit more specific, say that this is a security flaw that occurs in the processing of recovery volumes. The issue is caused by a lack of proper validation of user-supplied data. This can result in memory access beyond the end of an allocated buffer. Therefore, an attacker can exploit this vulnerability to execute code in the current process.
But all this can be solved just by downloading the most recent version of the program that its developers have released, for example. from this link. In this way, we will be able to continue working with this file compressor in complete safety and keeping our equipment protected.
