Bug 759398: Heap use-after-free in xmlDictComputeFastKey <https://bugzilla.gnome.org/show_bug.cgi?id=759398>
* parser.c: (xmlParseNCNameComplex): Store start position instead of a pointer to the name since the underlying buffer may change, resulting in a stale pointer being used. * result/errors/759398.xml: Added. * result/errors/759398.xml.err: Added. * result/errors/759398.xml.str: Added. * test/errors/759398.xml: Added test case.

<abstract>
|
||||
<p>The Extensible Markup Language (XML) is a subset of
|
||||
SGML that is completely described in this document. Its goal is to
|
||||
enable generic SGML to be served, received, and processed on the Web
|
||||
in the way that is now possible with HTML. XML has been designed for
|
||||
ease of implementation and for interoperability with both SGML and
|
||||
HTML.</p>
|
||||
</abstract>
|
||||
<status>
|
||||
<p>This document has been reviewed by W3C Members and
|
||||
other interested parties and has been endorsed by the
|
||||
Director as a W3C Recommendation. It is a stable
|
||||
document and may be used as reference material or cited
|
||||
as a normative reference from another document. W3C's
|
||||
role in making the Recommendation is to draw attention
|
||||
to the spPcification and to promote its widespread
|
||||
deployment. This enhances the functionality and
|
||||
interoperability of the Web.</p>
|
||||
<p>
|
||||
This document specifies a syntax created by subsetting an existing,
|
||||
widely used international text processing standard (Standard
|
||||
Generalized Markup Language, ISO 8879:1986(E) as amended and
|
||||
corrected) for use on the World Wide Web. It is a product of the W3C
|
||||
XML Activity, details of which can be found at <loc
|
||||
href='http://www.w3.org/XML'>http://www.w3.org/XML</loc>. A list of
|
||||
current W3C Recommendations and other technical documents can be found
|
||||
at <loc href='http://www.w3.org/TR'>http://www.w3.org/TR</loc>.
|
||||
</p>
|
||||
<p>This specification uses the term URI, which is defined by <bibref
|
||||
ref="Berners-Lee"/>, a work in progress expected to update <bibref
|
||||
ref="RFC1738"/> and <bibref ref="RFC1808"/>.

|
||||
<sitem>1997-12-02 : CMSMcQ : deal with as many corrections and
|
||||
comments from the proofreaders as possible:
|
||||
entify hard-coded document date in pubdate element,
|
||||
change expansion of entity WebSGML,
|
||||
update status description as per Dan Connolly (am not sure
|
||||
about refernece to Berners-Lee et al.),
|
||||
add 'The' to abstract as per WG decision,
|
||||
move Relationship to Existing Standards to back matter and
|
||||
combine with References,
|
||||
re-order back matter so normative appendices come first,
|
||||
re-tag back matter so informative appendices are tagged informdiv1,
|
||||
remove XXX XXX from list of 'normative' specs in prose,
|
||||
move some references from Other References to Normative References,
|
||||
add RFC 1738, 1808, and 2141 to Other References (they are not
|
||||
normative since we do not require the processor to enforce any
|
||||
rules based on them),
|
||||
add reference to 'Fielding draft' (Berners-Lee et al.),
|
||||
move notation section to end of body,
|
||||
drop URIchar non-terminal and use SkipLit instead,
|
||||
lose stray reference to defunct nonterminal 'markupdecls',
|
||||
move reference to Aho et al. into appendix (Tim's right),
|
||||
add prose note saying that hash marks and fragment identifiers are
|
||||
NOT part of the URI formally speaking, and are NOT legal in
|
||||
system identifiers (processor 'may' signal an error).
|
||||
Work through:
|
||||
Tim Bray reacting to James Clark,
|
||||
Tim Bray on his own,
|
||||
Eve Maler,
|
||||
|
||||
NOT DONE YET:
|
||||
change binary / text to unparsed / parsed.
|
||||
handle James's suggestion about < in attriubte values
|
||||
uppercase hex characters,
|
||||
namechar list,

|

<sitem>1997-12-01 : CMSMcQ : begin round of changes to incorporate

recent WG decisions and other corrections:

|
||||
correct wording of Faust quotation (restore dropped line),
|
||||
drop SDD from EncodingDecl,
|
||||
change text at version number 1.0,

<sitem>1997-06-30 : CMSMcQ : change date, some cosmetic changes,

changes to productions for choice, seq, Mixed, NotationType,

Enumeration. Follow James Clark's suggestion and prohibit

conditional sections in internal subset. TO DO: simplify

production for ignored sections as a result, since we don't

need to worry about parsers whi<! don't expand PErefs finding

Suppress old FINAL EDIT comments and some dead material.

Revise occurrences of % in grammar to exploit Henry Thompson's pun,
|

especially markupdecl and attdef.
|

Remove RMD requirement relating to element content (?).
|

</sitem>
|

<sitem>1997-06-28 : CMSMcQ : Various changes for 1 July draft:

Add text for draconian error handling (introduce

the term Fatal Error).

RE deleta est (changing wording from

original announcement to restrict the requirement to validating

parsers).

<sitem>1997 James Clark:
|
||||
Define the set of characters from which [^abc] subtracts.
|
||||
Charref should use just [0-9] not Digit.
|
||||
Location info needs cleaner treatment: remove? (ERB
|
||||
question).
|
||||
One example of a PI has wrong pic.
|
||||
Clarify discussion of encoding names.
|
||||
Encoding failure should lead to unspecified results; don't
|
||||
prescribe error recovery.
|
||||
Don't require exposure of entity boundaries.
|
||||
Ignore white space in element content.
|
||||
Reserve entity names of the form u-NNNN.
|
||||
Clarify relative URLs.
|
||||
And some of my own:
|
||||
Correct productions for content model: model cannot
|
||||
consist of a name, so "elements ::= cp" is no good.
|
||||
</sitem>

||||

||||
Add bibliographic refs to 10646, HyTime, Unicode.
|
||||
Rename old Cdata as MsData since it's <emph>only</emph> seen
|
||||
in marked sections. Call them attribute-value pairs not
|
||||
name-value pairs, except once. Internal subset is optional, needs

'?'. Implied attributes should be signaled to the app, not
|
||||
have values supplied by processor.</sitem>

||||
Streamline discussion of doctype decl syntax.
