CVE-2010-0424 – cronie: Race condition by setting timestamp of user's crontab file, when editing the file

https://notcve.org/view.php?id=CVE-2010-0424

The edit_cmd function in crontab.c in (1) cronie before 1.4.4 and (2) Vixie cron (vixie-cron) allows local users to change the modification times of arbitrary files, and consequently cause a denial of service, via a symlink attack on a temporary file in the /tmp directory. La funcion edit_cmd en crontab.c en (1) cronie anteriores a v1.4.4 y (2) Vixie cron (vixie-cron) permite a usuarios locales cambiar las horas de modificación de ficheros de forma arbitraria, y consecuentemente producir una denegación de servicio, a través de un ataque de enlace simbólico en un fichero temporal en el directorio /tmp. • http://git.fedorahosted.org/git/cronie.git?p=cronie.git%3Ba=commit%3Bh=9e4a8fa5f9171fb724981f53879c9b20264aeb61 http://lists.fedoraproject.org/pipermail/package-announce/2010-February/035762.html http://secunia.com/advisories/38700 http://secunia.com/advisories/38741 http://secunia.com/advisories/48104 http://www.securityfocus.com/bid/38391 https://bugzilla.redhat.com/show_bug.cgi?id=565809 https://access.redhat.com/security/cve/CVE-2010-0424 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
