We can do this because MacOS filepaths (alis type 2) are always converted to UNIX filepaths (alis type 18). --- libavformat/mov.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavformat/mov.c b/libavformat/mov.c index 2704dfb..70fa1e0 100644 --- a/libavformat/mov.c +++ b/libavformat/mov.c @@ -2301,7 +2301,7 @@ static int mov_open_dref(AVIOContext **pb, char *src, MOVDref *ref, { /* try relative path, we do not try the absolute because it can leak information about our system to an attacker */ - if (ref->nlvl_to > 0 && ref->nlvl_from > 0) { + if (ref->nlvl_to > 0 && ref->nlvl_from > 0 && ref->path[0] != '/') { char filename[1024]; char *src_path; int i, l; _______________________________________________ libav-commits mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-commits
