If you encounter a false positive, please report it here. You can be sure that this is a so-called false positive, an error - if you downloaded UniExtract from the official source at. Some anti-virus programs occasionally misdetect files inside UniExtract's program directory. Universal Extractor does not contain any malware. See the changelog for a complete log of all improvements.
#Uniextract vs 7zip update#
As the development of the original version has stopped and no update has been published for years, many forks (modified versions, maintained by volunteers from the community) have arisen. This program is an unofficial updated and extended version of the original UniExtract by Jared Breland. An overview of supported file types can be found here It can also deal with application installers, disk images and even game archives and other multimedia files.

Unlike most archiving programs, UniExtract is not limited to standard archives such as. If you are using 7-Zip portable, download and unpack version 18.01.Universal Extractor 2 is a tool designed to extract files from any type of extractable file. Currently the 7-Zip download page offers version 18.01. Update to version 18.01Īccording to the information in the blog post, both bugs were closed in 7-Zip version 18.00 beta. The vulnerability seems to be in the code since then. The relevant routine for the shrink decoder of 7-Zip was written by Igor Pavlov in 2005. The ZIP part of the program contains a heap buffer overflow vulnerability in the LZW shrink routine. Apparently, it is currently not activated because 7-Zip is linked to an outdated linker that does not support the flag.īecause there are different ways for attackers to corrupt the stack and heap, using it for remote code execution is straightforward, especially when no DEP is used. At least he will try to activate /NXCOMPAT for the next version. It also does not want to activate /GS, as it could affect the runtime and binary size. Pavlov, however, refused to activate /DYNAMICBASE.īackground: He prefers to create the binary files without a relocation table in order to achieve a minimum binary size. Dave discussed this topic with Igor Pavlov (the developer of 7-Zip) and tried to convince him to activate all three flags. In addition, 7-Zip is compiled without the /GS flag, so there is no stack monitoring. There you can see that DEP has been permanently deactivated.

For example, the following screenshot shows the latest version of 7-Zip 18.00 running on a fully updated Windows 8.1 x86: And DEP is enabled only on 64-bit Windows systems as well as in the 32-bit version of Windows 10. This means that 7-Zip runs on all Windows systems without ASLR. In the blog post, Dave says that the 7-Zip binary files for Windows were compiled without the compiler flags /NXCOMPAT and /DYNAMICBASE. This can be used to compromise memory (memory corruption).
#Uniextract vs 7zip rar#
PPMd, an implementation of Dmitry Shkarin's PPMII compression algorithm, can be used for version 3 of the RAR format.ĭave has now found a vulnerability in the implementation of the unpacking routine. The RAR code of 7-Zip is mostly based on a current UnRAR version. Dave found two vulnerabilities in 7-Zip in versions before 18.00. In Dave's blog landave.io there is a post 7-Zip: Multiple Memory Corruptions via RAR and ZIP reporting the details. informed me a few hours ago about the program's security problems (thanks for that).
#Uniextract vs 7zip archive#
7-Zip is a packer tool that supports different archive formats and is available for Windows and Linux – as well as unofficially for macOS.
