[Bug binutils/17597] New: NULL pointer dereference in opncls.c in bfd_get_debug_link_info().
https://sourceware.org/bugzilla/show_bug.cgi?id=17597 Bug ID: 17597 Summary: NULL pointer dereference in opncls.c in bfd_get_debug_link_info(). Product: binutils Version: unspecified Status: NEW Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: oxaa at gmail dot com I use tcc to compile simple source, but when i try to 'objdump -S -d a.out' it crushes with SIGSEGV. Reason is in opncls.c, function 'bfd_get_debug_link_info' in line: 'crc_offset = strlen(name) + 1;' because pointer name is NULL and strlen requries valid pointer. So is it problem of tcc(i mean this pointer can't be NULL) or problem of bfd? I add check for whether name is NULL or not and objdump seems work with this case. -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
