4Subject: [PATCH] Fix handling of parameter-entity references
5MIME-Version: 1.0
6Content-Type: text/plain; charset=UTF-8
7Content-Transfer-Encoding: 8bit
8
9There were two bugs where parameter-entity references could lead to an
10unexpected change of the input buffer in xmlParseNameComplex and
11xmlDictLookup being called with an invalid pointer.
12
13Percent sign in DTD Names
14=========================
15
16The NEXTL macro used to call xmlParserHandlePEReference. When parsing
17"complex" names inside the DTD, this could result in entity expansion
18which created a new input buffer. The fix is to simply remove the call
19to xmlParserHandlePEReference from the NEXTL macro. This is safe because
20no users of the macro require expansion of parameter entities.
21
22- xmlParseNameComplex
23- xmlParseNCNameComplex
24- xmlParseNmtoken
25
26The percent sign is not allowed in names, which are grammatical tokens.
27
28- xmlParseEntityValue
29
30Parameter-entity references in entity values are expanded but this
31happens in a separate step in this function.

44
45- xmlLoadEntityContent
46
47This function is only called from xmlStringLenDecodeEntities and
48entities are replaced in a separate step immediately after the function
49call.
50
51This bug could also be triggered with an internal subset and double
52entity expansion.
53
54This fixes bug 766956 initially reported by Wei Lei and independently by
55Chromium's ClusterFuzz, Hanno Böck, and Marco Grassi. Thanks to everyone
56involved.
57
58xmlParseNameComplex with XML_PARSE_OLD10
59========================================
60
61When parsing Names inside an expanded parameter entity with the
62XML_PARSE_OLD10 option, xmlParseNameComplex would call xmlGROW via the
63GROW macro if the input buffer was exhausted. At the end of the
64parameter entity's replacement text, this function would then call
65xmlPopInput which invalidated the input buffer.
66
67There should be no need to invoke GROW in this situation because the
68buffer is grown periodically every XML_PARSER_CHUNK_SIZE characters and,
69at least for UTF-8, in xmlCurrentChar. This also matches the code path
70executed when XML_PARSE_OLD10 is not set.
71
72This fixes bugs 781205 (CVE-2017-9049) and 781361 (CVE-2017-9050).
73Thanks to Marcel Böhme and Thuan Pham for the report.
74
75Additional hardening
76====================
77
78A separate check was added in xmlParseNameComplex to validate the
79buffer size.
