Package: proot
Version: 5.1.0-1.1
Severity: normal
Tags: upstream
Hello,
It seems proot 5.1.0-1.1, as found in Debian Sid as I am reporting this, is
unusable.
How to reproduce?
$ # Work around https://github.com/proot-me/PRoot/issues/106
$ export PROOT_NO_SECCOMP=1
$ proot ls
proot error: can't write the loader: Bad address
proot error: execve("/bin/ls"): No such file or directory
proot info: possible causes:
* the program is a script but its interpreter (eg. /bin/sh) was not found;
* the program is an ELF but its interpreter (eg. ld-linux.so) was not
found;
* the program is a foreign binary but qemu was not specified;
* qemu does not work correctly (if specified);
* the loader was not found or doesn't work.
fatal error: see `proot --help`.
Expected outcome: this command should have listed the current directory.
A short investigation reveals that proot fails to determine the size of the
binary loader (it gets a garbage value), leading to that "can't write the
loader" error when the said garbage value is fed to write().
Fortunately, a fix is available upstream: https://github.com/proot-
me/PRoot/pull/108
And I can confirm that building the "hotfixLoader" branch makes proot usable
again.
Cheers,
Xavier.
