Re: [libvirt] [PATCHv2 2/2] openvz: avoid potential buffer overflow

2010/12/7 Eric Blake <eblake@redhat.com>:

* src/openvz/openvz_conf.c (openvzLoadDomains): Replace unsafe sscanf with safe direct parsing. (openvzGetVEID): Avoid lost integer overflow detection. (openvzAssignUUIDs): Likewise, and detect readdir failure. ---

v2: new patch; plugs a potential security hole, since *scanf("%s",fixed_width_buffer) is exploitable, but the exploit could only happen if /usr/sbin/vzlist is compromised.
