Anyway, couple of security flaws were found by Florian during security review: * Issue #1: Log file created with insecure (world-writable) permissions https://bugzilla.redhat.com/show_bug.cgi?id=911122 A security flaw was found in the way Trace module of WiMAX, an user space daemon for the Intel 2400m Wireless WiMAX link, used to set permissions when opening the log file (was created with world-readable / writable permissions). A local attacker could use this flaw to, in an unauthorized way, alter the content of WiMAX daemon log file (possibly leading to un-enforced actions to be performed by system administrator). * Issue #2: (OSAL crypt module): By setting encrypted password writes unencrypted passwords to log files https://bugzilla.redhat.com/show_bug.cgi?id=911121 A security flaw was found in the way OSAL crypt module of WiMAX, an user space daemon for the Intel 2400m Wireless WiMAX link, used to perform its internal encrypted password setting action (a failed attempt to set the encrypted password was logged into the WiMAX's log file with provided password logged in plaintext form). A local attacker could use this flaw to obtain sensitive information or conduct unauthorized actions on behalf of the user setting the encrypted password. * Issue #3: Supplicant agent ships RSA private key in the package https://bugzilla.redhat.com/show_bug.cgi?id=911126 A security flaw was found in the way supplicant agent of WiMAX, an user space daemon for the Intel 2400m Wireless WiMAX link, used to manage its private key (private key was shipped together with the source code). A local attacker could use this flaw to obtain security sensitive data or, to conduct actions on behalf of private key owner. * Issue #4: Three integer overflows, leading to heap-based buffer overflows when handling PDUs for L5 connections https://bugzilla.redhat.com/show_bug.cgi?id=911129 Three cases of integer overflow, leading to heap-based buffer overflow flaw, were found in the way socket dispatcher and connector modules for L5 connections of WiMAX, an user space daemon for the Intel 2400m Wireless WiMAX link, used to handle certain payload data units (PDUs) for L5 connections. A remote attacker could issue a connection request with specially-crafted PDU value that, when processed would lead to socket dispatcher / connector module crash or, potentially, arbitrary code execution with the privileges of the user running these modules. There are no patches for these issues yet. They were checked previously privately with Dan Williams and the suggestion was to file public bugs even when there are no patches available for these. Could you allocate CVE ids for these? Thank you && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team
