Description Steve Grubb 2011-07-04 14:58:42 UTC

Description of problem:
The following programs seem to require an executable stack:
/usr/libexec/p7zip/7za
/usr/libexec/p7zip/7z
/usr/libexec/p7zip/7z.so
/usr/libexec/p7zip/7zCon.sfx

To check, do this:
# eu-readelf -l /usr/libexec/p7zip/7za | grep GNU_STACK
  GNU_STACK      0x000000 0x0000000000000000 0x0000000000000000 0x000000 0x000000 RWE 0x8

Should be just "RW" and no "E".

# rpm -qf /usr/libexec/p7zip/7za
p7zip-9.13-2.fc15.x86_64

Additional info:
The program should be fixed so that an executable stack is not needed.

Comment 1 Matthias Saou 2011-07-26 15:46:07 UTC

This has already been reported upstream :
http://sourceforge.net/tracker/?func=detail&aid=3283518&group_id=111810&atid=660493

I'll include a patch to get this fixed in the Fedora package.
