CVSS: 7.2EPSS: 0%CPEs: 13EXPL: 2CVE-2009-1041 – FreeBSD 7.0/7.1 - 'ktimer' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2009-1041
The ktimer feature (sys/kern/kern_time.c) in FreeBSD 7.0, 7.1, and 7.2 allows local users to overwrite arbitrary kernel memory via an out-of-bounds timer value. La funcionalidad ktimer (sys/kern/kern_time.c) de FreeBSD v7.0, v7.1 y v7.2, permite a usuarios locales sobrescribir a su elección la memoria del kernel a través de un valor timer fuera de rango. • https://www.exploit-db.com/exploits/8261 http://security.freebsd.org/advisories/FreeBSD-SA-09:06.ktimer.asc http://www.securityfocus.com/bid/34196 http://www.securitytracker.com/id?1021882 https://exchange.xforce.ibmcloud.com/vulnerabilities/49362 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

sys_term.c in telnetd in FreeBSD 7.0-RELEASE and other 7.x versions deletes dangerous environment variables with a method that was valid only in older FreeBSD distributions, which might allow remote attackers to execute arbitrary code by passing a crafted environment variable from a telnet client, as demonstrated by an LD_PRELOAD value that references a malicious library. sys_term.c en telnetd en FreeBSD v7.0-RELEASE y otras v7.x borra variables de entorno peligrosas con un método que solo fue valido en distribuciones antiguas de FreeBSD, lo que permite a atacantes remotos ejecutar código de su elección a través de un cliente de telnet de una variable de entorno manipulada, como se demuestra mediante el valor LD_PRELOAD que hace referencia a una librería maliciosa. • https://www.exploit-db.com/exploits/8055 http://lists.grok.org.uk/pipermail/full-disclosure/2009-February/067954.html http://security.freebsd.org/advisories/FreeBSD-SA-09:05.telnetd.asc http://www.securityfocus.com/bid/33777 https://exchange.xforce.ibmcloud.com/vulnerabilities/48780 • CWE-16: Configuration CWE-264: Permissions, Privileges, and Access Controls •
