CVE-2008-3531 – FreeBSD 7.0/7.1 - 'vfs.usermount' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2008-3531
Stack-based buffer overflow in sys/kern/vfs_mount.c in the kernel in FreeBSD 7.0 and 7.1, when vfs.usermount is enabled, allows local users to gain privileges via a crafted (1) mount or (2) nmount system call, related to copying of "user defined data" in "certain error conditions." Desbordamiento de búfer basado en pila en sys/kern/vfs_mount.c del núcleo de FreeBSD 7.0 y 7.1, cuando vfs.usermount está habilitado; permite a usuarios locales obtener privilegios a través de una llamada al sistema manipulada a (1) mount o (2) nmount. Está relacionado con la copia de "datos definidos por el usuario" en "determinadas condiciones de error". • https://www.exploit-db.com/exploits/9082 http://security.FreeBSD.org/advisories/FreeBSD-SA-08:08.nmount.asc http://www.securityfocus.com/bid/31002 http://www.securitytracker.com/id?1020816 https://exchange.xforce.ibmcloud.com/vulnerabilities/45143 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2008-3890
https://notcve.org/view.php?id=CVE-2008-3890
The kernel in FreeBSD 6.3 through 7.0 on amd64 platforms can make an extra swapgs call after a General Protection Fault (GPF), which allows local users to gain privileges by triggering a GPF during the kernel's return from (1) an interrupt, (2) a trap, or (3) a system call. El kernel de FreeBSD 6.3 hasta 7.0 en las plataformas de amd64 , puede hacer excesivas llamadas swapgs después de un Fallo General de Protección -General Protection Fault (GPF)-; esto permite a usuarios locales obtener privilegios provocando un Fallo General de Protección durante el regreso del kernel desde (1) una interrupción, (2) un paso del proceso de modo de usuario a modo kernel, o (3) una llamada al sistema. • http://secunia.com/advisories/31743 http://security.freebsd.org/advisories/FreeBSD-SA-08:07.amd64.asc http://www.securityfocus.com/bid/31003 http://www.securitytracker.com/id?1020815 https://exchange.xforce.ibmcloud.com/vulnerabilities/44905 • CWE-264: Permissions, Privileges, and Access Controls •
