| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [NVD] -- https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-6131 The demangler in GNU Libiberty allows remote attackers to cause a denial of service (infinite loop, stack overflow, and crash) via a cycle in the references of remembered mangled types. [BZ #71696] -- https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71696 2016-08-04 Marcel Böhme <boehme.marcel@gmail.com> PR c++/71696 * cplus-dem.c: Prevent infinite recursion when there is a cycle in the referencing of remembered mangled types. (work_stuff): New stack to keep track of the remembered mangled types that are currently being processed. (push_processed_type): New method to push currently processed remembered type onto the stack. (pop_processed_type): New method to pop currently processed remembered type from the stack. (work_stuff_copy_to_from): Copy values of new variables. (delete_non_B_K_work_stuff): Free stack memory. (demangle_args): Push/Pop currently processed remembered type. (do_type): Do not demangle a cyclic reference and push/pop referenced remembered type. cherry-picked from commit of git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@239143 138bc75d-0d04-0410-961f-82ee72b054a4 (From OE-Core rev: 3c288b181a4cfecc80b48994f4dd2df285e4d1d0) (From OE-Core rev: 96a16c4181d18b8580dad243350d589586cb2b07) Signed-off-by: Yuanjie Huang <yuanjie.huang@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
