FreeBSD : multiple buffer overflows in xboing (e25566d5-6d3f-11d8-83a4-000a95bc6fae)

medium Nessus Plugin ID 37706

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Steve Kemp reports (in a Debian bug submission) :

Due to improper bounds checking it is possible for a malicious user to gain a shell with membership group 'games'. (The binary is installed setgid games).

Environmental variables are used without being bounds-checked in any way, from the source code :

highscore.c : /* Use the environment variable if it exists */ if ((str = getenv('XBOING_SCORE_FILE')) != NULL) strcpy(filename, str); else strcpy(filename, HIGH_SCORE_FILE);

misc.c : if ((ptr = getenv('HOME')) != NULL) (void) strcpy(dest, ptr);

Neither of these checks are boundschecked, and will allow arbitary shell code to be run.

Solution

Update the affected package.
