============================================ fcrontab Information Disclosure Vulnerability March 3, 2010 CVE-2010-0792 ============================================ ==Description== fcrontab, part of the fcron scheduler, is vulnerable to several race conditions that allow a local attacker to use symbolic links to read unauthorized files. On systems where fcrontab is installed with its own "fcron" group, this allows an attacker to read other non-root users' crontabs and fcron configuration files. On systems where fcrontab is installed suid root, this allows an attacker to read arbitrary files. ==Solution== The developer has released a new version, 3.0.5, to address these vulnerabilities. It is available for download on the developer's website, http://fcron.free.fr. Users are advised to recompile from source or download updated packages from downstream distributors when they become available. ==Credits== This vulnerability was discovered by Dan Rosenberg (dan.j.rosenberg (at) gmail (dot) com [email concealed]). Thanks to Thibault Godouet for his prompt response and new release. ==References== CVE identifier CVE-2010-0792 has been assigned to this issue.
