-Subject: [PATCH 06/40] CVE-2014-0209: integer overflow of realloc() size in
- lexAlias() from xorg/lib/libXfont commit
- 05c8020a49416dd8b7510cbba45ce4f3fc81a7dc
-
-lexAlias() reads from a file in a loop. It does this by starting with a
-64 byte buffer. If that size limit is hit, it does a realloc of the
-buffer size << 1, basically doubling the needed length every time the
-length limit is hit.
-
-Eventually, this will shift out to 0 (for a length of ~4gig), and that
-length will be passed on to realloc(). A length of 0 (with a valid
-pointer) causes realloc to free the buffer on most POSIX platforms,
-but the caller will still have a pointer to it, leading to use after
-free issues.
