The Xsession script, as used by X Display Manager (xdm) in NetBSD before 20060212, X.Org before 20060317, and Solaris 8 through 10 before 20061006, allows local users to overwrite arbitrary files, or read another user's Xsession errors file, via a symlink attack on a /tmp/xses-$USER file. La secuencia de comandos Xsession, tambien usado por X Display Manager (xdm) en NetBSD anterior a 12/02/2006, X.Org anterior a 17/03/2006, y Solaris 8 hasta la 10 anterior a 06/10/2006, permiten a un usuario local sobre escribir archivos de su elección, o leer otros ficheros de errores de usuarios de Xsession, a través de un ataque de enlaces simbólicos sobre un archivo/tmp/xses-$USER. • http://secunia.com/advisories/22992 http://securitytracker.com/id?1017015 http://sunsolve.sun.com/search/document.do?assetkey=1-26-102652-1 http://support.avaya.com/elmodocs2/security/ASA-2006-250.htm http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=32805 https://bugs.freedesktop.org/show_bug.cgi?id=5898 https://exchange.xforce.ibmcloud.com/vulnerabilities/29427 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A2205 •

The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment's reference count when the vm_map_find function fails, which could allow local users to gain read or write access to a portion of kernel memory and gain privileges. La llamada de sistema shmat en el interfaz de Memoria Compartida de Sistema V de FreeBSD 5.2 y anteriores, NetBSD 1.3 y anteriores, y OpenBSD 2.6 y anteriores, no decrementa adecuadamente un contador de referencias de segmentos de memoria compartidos cuando al función vm_map_find falla, lo que podría permitir a usuarios locales ganar acceso de lectura y escritura a una porción de memoria del kernel y ganar privilegios. • https://www.exploit-db.com/exploits/23655 ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:02.shmat.asc ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2004-004.txt.asc http://marc.info/?l=bugtraq&m=107608375207601&w=2 http://www.openbsd.org/errata33.html#sysvshm http://www.osvdb.org/3836 http://www.pine.nl/press/pine-cert-20040201.txt http://www.securityfocus.com/bid/9586 https://exchange.xforce.ibmcloud.com/vulnerabilities/15061 •

Race condition in exec in OpenBSD 4.0 and earlier, NetBSD 1.5.2 and earlier, and FreeBSD 4.4 and earlier allows local users to gain privileges by attaching a debugger to a process before the kernel has determined that the process is setuid or setgid. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-02:08.exec.asc ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2002-001.txt.asc http://www.osvdb.org/19475 http://www.securityfocus.com/bid/3891 https://exchange.xforce.ibmcloud.com/vulnerabilities/7945 •
