Pushes pointers on an automatic array without checking for overflow. Can be used for DoS attacks. Will be extremely hard to make it execute arbitrary code. Relevant upstream patch:  http://www.swi-prolog.org/git/pl.git/commitdiff/a9a6fc8a2a9cf3b9154b490a4b1ffaa8be4d723c References:  https://lists.iai.uni-bonn.de/pipermail/swi-prolog/2012/009428.html  https://bugzilla.redhat.com/show_bug.cgi?id=891577 * Issue #2 - from : ====================== * SECURITY: Possible buffer overflows when expanding file-names with long paths. Affects expand_file_name/2. Can lead to crashes (DoS attacks) and possibly execution of arbitrary code if an attacker can control the names of the files searched for, e.g., if expand_file_name/2 is used in a directory to which an attacker can upload files for which he can control the name. Relevant upstream patch:  http://www.swi-prolog.org/git/pl.git/commitdiff/b2c88972e7515ada025e97e7d3ce3e34f81cf33e References:  https://lists.iai.uni-bonn.de/pipermail/swi-prolog/2012/009428.html  https://bugzilla.redhat.com/show_bug.cgi?id=891577 Could you allocate CVE ids for these? (iilc two should be enough) Thank you && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team
