The breakage was relatively +subtle: it set all hour components to 0, while everything else was +parsed successfully. + +But the problem is really that sscanf wrote 1 byte past the sep +variable (or more, for invalid/specially prepared input). The %[..] +format specifier is unbounded. Fix that by letting sscanf drop the +parsed contents with "*", and also make it skip only one input +character by adding "1" (=> "%*1[..."). + +The out of bound write could easily lead to security issues. + +Also, this change makes .srt subtitle parsing slightly more strict. +Strictly speaking this is an unrelated change, but do it anyway. It's +more correct. +--- + sub/subreader.c | 8 ++++---- + 1 file changed, 4 insertions(+), 4 deletions(-) + + (foutrelis: adjusted variable names in first hunk to apply to mplayer) + +diff --git a/sub/subreader.c b/sub/subreader.c +index 23da4c7..0f1b6c9 100644 +--- a/sub/subreader.c ++++ b/sub/subreader.c +@@ -386,14 +386,14 @@ static subtitle *sub_ass_read_line_subviewer(stream_t *st, subtitle *current, + int h1, m1, s1, ms1, h2, m2, s2, ms2, j = 0; + + while (!current->text[0]) { +- char line[LINE_LEN + 1], full_line[LINE_LEN + 1], sep; ++ char line[LINE_LEN + 1], full_line[LINE_LEN + 1]; + int i; + + /* Parse SubRip header */ + if (!stream_read_line(st, line, LINE_LEN, utf16)) + return NULL; +- if (sscanf(line, "%d:%d:%d%[,.:]%d --> %d:%d:%d%[,.:]%d", +- &h1, &m1, &s1, &sep, &ms1, &h2, &m2, &s2, &sep, &ms2) < 10) ++ if (sscanf(line, "%d:%d:%d%*1[,.:]%d --> %d:%d:%d%*1[,.:]%d", ++ &h1, &m1, &s1, &ms1, &h2, &m2, &s2, &ms2) < 8) + continue; + + current->start = a1 * 360000 + a2 * 6000 + a3 * 100 + a4 / 10; +@@ -450,7 +450,7 @@ static subtitle *sub_read_line_subviewer(stream_t *st,subtitle *current, + return sub_ass_read_line_subviewer(st, current, args); + while (!current->text[0]) { + if (!stream_read_line (st, line, LINE_LEN, utf16)) return NULL; +- if ((len=sscanf (line, "%d:%d:%d%[,.:]%d --> %d:%d:%d%[,.:]%d",&a1,&a2,&a3,(char *)&i,&a4,&b1,&b2,&b3,(char *)&i,&b4)) < 10) ++ if ((len=sscanf (line, "%d:%d:%d%*1[,.:]%d --> %d:%d:%d%*1[,.:]%d",&a1,&a2,&a3,&a4,&b1,&b2,&b3,&b4)) < 8) + continue; + current->start = a1*360000+a2*6000+a3*100+a4/10; + current->end = b1*360000+b2*6000+b3*100+b4/10; +-- +1.8.1.6 + |
