UnknownEPSS 2.04%

Last modified

CVE-2005-4474 is a vulnerability of currently unknown severity. Buffer overflow in the "Add to archive" command in WinRAR 3.51 allows user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code by tricking the user into adding a file whose filename contains a non-default code page and non-ANSI characters, as demonstrated using a Chinese filename, possibly due to buffer expansion when using the WideCharToMultiByte API. NOTE: it is not clear whether this problem can be exploited for code execution. EPSS estimates a 2.04% chance of exploitation in the next 30 days.
