This falls under the notion of "protection mechanism works less securely than advertised" so is a clear case for inclusion in CVE. Use CVE-2008-5110. Also - is the chdir supposed to come BEFORE or AFTER? The CERT secure coding rules here: https://www.securecoding.cert.org/confluence/display/cplusplus/FIO16-CPP.+Limit+access+to+files+by+creating+a+jail suggest it might be safer AFTER, not before, due to some race condition possibilities. - Steve ====================================================== Name: CVE-2008-5110 Status: Candidate URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5110 Reference: CONFIRM:http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505791 Reference: MLIST:[oss-security] 20081117 CVE Request (syslog-ng) Reference: URL:http://www.openwall.com/lists/oss-security/2008/11/17/3 syslog-ng does not call chdir before it calls chroot, which might allow attackers to escape the intended jail. NOTE: this is only a vulnerability when a separate vulnerability is present.
