The code in xz_decomp which attempts to verify the checksum -and length of the expanded data fails if the checksum or length at the end of -the file crosses a 1024 byte boundary. It calls gz_next4 to get those two -values. This function uses the stream state in state->zstrm, but calls -xz_avail which uses the state->strm stream info. This causes gz_next4 to -signal a premature EOF if the data it is fetching crosses a 1024 byte boundary. ---- - xzlib.c | 26 ++++++++++++++++++++++---- - 1 file changed, 22 insertions(+), 4 deletions(-) - -diff --git a/xzlib.c b/xzlib.c -index 928bd17..cd045fa 100644 ---- a/xzlib.c -+++ b/xzlib.c -@@ -245,6 +245,20 @@ xz_avail(xz_statep state) - return 0; - } - -+#ifdef HAVE_ZLIB_H -+static int -+xz_avail_zstrm(xz_statep state) -+{ -+ int ret; -+ state->strm.avail_in = state->zstrm.avail_in; -+ state->strm.next_in = state->zstrm.next_in; -+ ret = xz_avail(state); -+ state->zstrm.avail_in = (uInt) state->strm.avail_in; -+ state->zstrm.next_in = (Bytef *) state->strm.next_in; -+ return ret; -+} -+#endif -+ - static int - is_format_xz(xz_statep state) - { -@@ -314,6 +328,10 @@ is_format_lzma(xz_statep state) - #define NEXT() ((strm->avail_in == 0 && xz_avail(state) == -1) ? -1 : \ - (strm->avail_in == 0 ? -1 : \ - (strm->avail_in--, *(strm->next_in)++))) -+/* Same thing, but from zstrm */ -+#define NEXTZ() ((strm->avail_in == 0 && xz_avail_zstrm(state) == -1) ? -1 : \ -+ (strm->avail_in == 0 ? -1 : \ -+ (strm->avail_in--, *(strm->next_in)++))) - - /* Get a four-byte little-endian integer and return 0 on success and the value - in *ret.
