Category: None Group: None Status: Open Resolution: None Priority: 5 Private: Yes Submitted By: https://www.google.com/accounts () Assigned to: Nobody/Anonymous (nobody) Summary: buffer overruns in pidfile handling Initial Comment: Hello, while performing an audit of vde2 (https://bugs.launchpad.net/ubuntu/+source/vde2/+bug/776818) I found a bug; it may even be a security bug. If you decide this is a security issue, please contact the linux-distros security list to coordinate a release and request a CVE number. (See http://oss-security.openwall.org/wiki/mailing-lists/distros for details on using the linux-distros list. Note especially that [vs] is required in the Subject: header.) static void save_pidfile() { if(pidfile[0] != '/') strncat(pidfile_path, pidfile, PATH_MAX - strlen(pidfile_path)); else strcpy(pidfile_path, pidfile); If programs with this definition are executed with -p <more than PATH_MAX chars>, the pidfile_path heap array is overflowed and undefined behavior, including potential security problems, can result.
