1libxml2-2.9.4: Fix CVE-2016-4658
2

4
5xpointer: Disallow namespace nodes in XPointer points and ranges
6
7Namespace nodes must be copied to avoid use-after-free errors.
8But they don't necessarily have a physical representation in a
9document, so simply disallow them in XPointer ranges.

4Subject: [PATCH] Fix XPointer paths beginning with range-to
5
6The old code would invoke the broken xmlXPtrRangeToFunction. range-to
7isn't really a function but a special kind of location step. Remove
8this function and always handle range-to in the XPath code.
9
10The old xmlXPtrRangeToFunction could also be abused to trigger a
11use-after-free error with the potential for remote code execution.
12
13Found with afl-fuzz.
14
15Fixes CVE-2016-5131.

13=========================
14
15The NEXTL macro used to call xmlParserHandlePEReference. When parsing
16"complex" names inside the DTD, this could result in entity expansion
17which created a new input buffer. The fix is to simply remove the call
18to xmlParserHandlePEReference from the NEXTL macro. This is safe because
19no users of the macro require expansion of parameter entities.
20
21- xmlParseNameComplex
22- xmlParseNCNameComplex
23- xmlParseNmtoken
24
25The percent sign is not allowed in names, which are grammatical tokens.
26
27- xmlParseEntityValue
28
29Parameter-entity references in entity values are expanded but this
30happens in a separate step in this function.
31
32- xmlParseSystemLiteral
33
34Parameter-entity references are ignored in the system literal.
35
36- xmlParseAttValueComplex
37- xmlParseCharDataComplex
38- xmlParseCommentComplex
39- xmlParsePI
40- xmlParseCDSect
41
42Parameter-entity references are ignored outside the DTD.
43
44- xmlLoadEntityContent
45
46This function is only called from xmlStringLenDecodeEntities and
47entities are replaced in a separate step immediately after the function
48call.
49
50This bug could also be triggered with an internal subset and double
51entity expansion.
52
53This fixes bug 766956 initially reported by Wei Lei and independently by
54Chromium's ClusterFuzz, Hanno Böck, and Marco Grassi. Thanks to everyone
55involved.
56
57xmlParseNameComplex with XML_PARSE_OLD10
58========================================
59
60When parsing Names inside an expanded parameter entity with the
61XML_PARSE_OLD10 option, xmlParseNameComplex would call xmlGROW via the
62GROW macro if the input buffer was exhausted. At the end of the
63parameter entity's replacement text, this function would then call
64xmlPopInput which invalidated the input buffer.
65
66There should be no need to invoke GROW in this situation because the
67buffer is grown periodically every XML_PARSER_CHUNK_SIZE characters and,
68at least for UTF-8, in xmlCurrentChar. This also matches the code path
69executed when XML_PARSE_OLD10 is not set.
70
71This fixes bugs 781205 (CVE-2017-9049) and 781361 (CVE-2017-9050).
72Thanks to Marcel Böhme and Thuan Pham for the report.
73
74Additional hardening
75====================
76
77A separate check was added in xmlParseNameComplex to validate the
78buffer size.

1libxml2-2.9.4: Avoid reparsing and simplify control flow in xmlParseStartTag2
2

4
5parser: Avoid reparsing in xmlParseStartTag2
6
7The code in xmlParseStartTag2 must handle the case that the input
8buffer was grown and reallocated which can invalidate pointers to
9attribute values. Before, this was handled by detecting changes of
10the input buffer "base" pointer and, in case of a change, jumping
11back to the beginning of the function and reparsing the start tag.
12
13The major problem of this approach is that whether an input buffer is
14reallocated is nondeterministic, resulting in seemingly random test
15failures. See the mailing list thread "runtest mystery bug: name2.xml
16error case regression test" from 2012, for example.
17
18If a reallocation was detected, the code also made no attempts to
19continue parsing in case of errors which makes a difference in
20the lax "recover" mode.
21
22Now we store the current input buffer "base" pointer for each (not
23separately allocated) attribute in the namespace URI field, which isn't
24used until later. After the whole start tag was parsed, the pointers to
25the attribute values are reconstructed using the offset between the
26new and the old input buffer. This relies on arithmetic on dangling
27pointers which is technically undefined behavior. But it seems like
28the easiest and most efficient fix and a similar approach is used in
29xmlParserInputGrow.
30
31This changes the error output of several tests, typically making it
32more verbose because we try harder to continue parsing in case of errors.
33
34(Another possible solution is to check not only the "base" pointer
35but the size of the input buffer as well. But this would result in
36even more reparsing.)
37
38Remove some goto labels and deduplicate a bit of code after handling
39namespaces.
40
41There were two bugs where parameter-entity references could lead to an
42unexpected change of the input buffer in xmlParseNameComplex and
43xmlDictLookup being called with an invalid pointer.
