Title: Vixie Cron Buffer Overflow Vulnerability
Severity: INFO
Description:
The version of Vixie cron that ships with RedHat versions 4.2, 5.2 and 6.0 is vulnerable to a local buffer overflow attack. By utilizing the MAILTO environment variable, a buffer can be overflown in the cron_popen() function, allowing an attacker to execute arbitrary code. Vixie cron daemon is installed setuid root by default, allowing for a local root compromise. Recent versions of Debian GNU/Linux have been confirmed to not be vulnerable to this attack.
Affected Products:
- RedHat Linux 4.2.0
- RedHat Linux 5.2.0 i386
- RedHat Linux 6.0.0
- S.u.S.E. Linux 6.0.0
