Instead, do not treat the buffer +as an ASCII C-string. We calculate the count based on the return value +of memchr, instead of strlen. + +Fixes: CVE-2022-32292 +--- + gweb/gweb.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/gweb/gweb.c b/gweb/gweb.c +index 12fcb1d8..13c6c5f2 100644 +--- a/gweb/gweb.c ++++ b/gweb/gweb.c +@@ -918,7 +918,7 @@ static gboolean received_data(GIOChannel *channel, GIOCondition cond, + } + + *pos = '\0'; +- count = strlen((char *) ptr); ++ count = pos - ptr; + if (count > 0 && ptr[count - 1] == '\r') { + ptr[--count] = '\0'; + bytes_read--; +-- +cgit + |
