  • UPX 3.04 and prior packed programs won't run in Ubuntu 9.10

    Hey Guys ... Ubuntu broke upx packed .elf files again. This time 9.10. I use --force-execve --best --crp-ms=999999 --nrv2d it's a open watcom .elf produced program and the force-execve was needed to fix up prior version to work with ubuntu .. now nothing works. Is there a fix/work around?.

    > The win32 version of upx.exe and the executables compressed with it are being (falsely?) This had been reported already 1'000'000'000'000 times. UPX is UPX'ed itself as well. Bug authors of mcafee and esafe about this "problem".

  • Followup: RE: How to restore stripped headers from UPX

    Hehe ... many utils to strip UPX headers around (license violation ?), many stripped EXE's (???), but I haven't yet seen any tool to restore them. It's definitely possible (as long as the file runs), but one migh have to look into the stub disassembly.

  • OT: Contacting Markus Oberhumer

    Hi, Apologies for this very off-topic topic. I've been trying to reach Markus Oberhumer for a couple of months by e-mail and phone to his oberhumer.com company. I've received no reply what so ever. Does anyone know of a way to get in contact with him?? Thanks, Simon.

    Where exactly is the upx source code repository? I found http://upx.hg.sourceforge.net/hgweb/upx/upx/, but last commit was 7 months ago. Is there some other repository?.

  • Comment: linux/elf386 much worse w/ --ultra-brute than --best --lzma

    Class PackLinuxElf does nothing special here. There is a side effect in PackExe::PackExe(), file p_exe.cpp: // disable lzma for "--brute" unless explicitly given "--lzma" if (opt->all_methods_use_lzma && !opt->method_lzma_seen) opt->all_methods_use_lzma = false; which is triggered during the Visit to find he proper packer: #0 PackExe::PackExe(struct InputFile *...
