* xpath: Remove remaining references to valueFrameNick Wellnhofer2023-04-301-1/+0
| | | | Fixes #529.
* Don't use sizeof(xmlChar) or sizeof(char)Nick Wellnhofer2022-09-011-1/+1
|
* Remove explicit integer castsNick Wellnhofer2022-09-011-7/+7
| | | | | | | | | | | | | | | | | | | | Remove explicit integer casts as final operation - in assignments - when passing arguments - when returning values Remove casts - to the same type - from certain range-bound values The main motivation is that these explicit casts don't change the result of operations and only render UBSan's implicit-conversion checks useless. Removing these casts allows UBSan to detect cases where truncation or sign-changes occur unexpectedly. Document some explicit casts as truncating and add a few missing ones.
* Consolidate private header filesNick Wellnhofer2022-08-261-0/+2
| | | | | | | | | | | Private functions were previously declared - in header files in the root directory - in public headers guarded with IN_LIBXML - in libxml.h - redundantly in source files that used them. Consolidate all private header files in include/private.
* Implement xpath1() XPointer schemeNick Wellnhofer2022-04-211-2/+5
| | | | See https://www.w3.org/2005/04/xpointer-schemes/
* Add configuration flag for XPointer locations supportNick Wellnhofer2022-04-211-2/+18
| | | | | | | | | | | | | | | | | | | | | Add a new configuration flag that controls whether the outdated support for XPointer locations (ranges and points) is enabled. --with-xptr-locs # Autotools LIBXML2_WITH_XPTR_LOCS # CMake The latest spec for what it essentially an XPath extension seems to be this working draft from 2002: https://www.w3.org/TR/xptr-xpointer/ The xpointer() scheme is listed as "being reviewed" in the XPointer registry since at least 2006. libxml2 seems to be the only modern software that tries to implement this spec, but the code has many bugs and quality issues. The flag defaults to "off" and support for this extensions has to be requested explicitly. The relevant API functions are deprecated.
* Fix potential double-free in xmlXPtrStringRangeFunctionNick Wellnhofer2022-03-051-0/+1
| | | | | | | Fix double-free in an unlikely error condition. Thanks to Wentao Liang for the report. Fixes #341.
* Remove DOCBparserNick Wellnhofer2022-03-041-3/+0
| | | | | | | This code has been broken and deprecated since version 2.6.0, released in 2003. Because of a bug in commit 961b535c, DOCBparser.c was never compiled since 2012. I couldn't find a Debian package using any of its symbols, so it seems safe to remove this module.
* Remove elfgcchack.hNick Wellnhofer2022-02-201-2/+0
| | | | | The same optimization can be enabled with -fno-semantic-interposition since GCC 5. clang has always used this option by default.
* Don't normalize namespace URIs in XPointer xmlns() schemeNick Wellnhofer2022-02-041-25/+1
| | | | | | | | Namespace URIs should be compared without escaping or unescaping: https://www.w3.org/TR/REC-xml-names/#NSNameComparison Fixes #289.
* xmlAddChild() and xmlAddNextSibling() may not attach their second argumentDavid Kilzer2022-01-251-7/+6
| | | | | | | | | Use the return value of xmlAddChild() and xmlAddNextSibling() instead of the second argument directly. Found by OSS-Fuzz. Fixes #316
* Fix handling of ctxt->base in xmlXPtrEvalXPtrPartNick Wellnhofer2022-01-251-12/+25
| | | | | | | | | | Also set ctxt->base when updating ctxt->cur. Always restore ctxt->cur on error. Avoids integer truncation and wrong column numbers in xmlXPathErr. Stop hiding modification of ctxt members behind a macro. Found with UBSan.
* Fix null pointer deref in xmlXPtrRangeInsideFunctionNick Wellnhofer2020-12-061-4/+6
| | | | Found by OSS-Fuzz.
* Fix memory leaks in XPointer string-range functionNick Wellnhofer2020-10-031-14/+27
| | | | Found by OSS-Fuzz.
* Don't call xmlXPathInit directlyNick Wellnhofer2020-09-181-1/+1
| | | | | | Call xmlInitParser which uses a lock to avoid race conditions. Fixes #184.
* Fix typosNick Wellnhofer2020-03-081-4/+4
| | | | Resolves #133.
* Large batch of typo fixesJared Yanovich2019-09-301-2/+2
| | | | Closes #109.
* Check for integer overflow in xmlXPtrEvalChildSeqNick Wellnhofer2019-03-291-2/+12
| | | | Found with libFuzzer and UBSan.
* Fix -Wenum-compare warningsNick Wellnhofer2017-11-271-2/+0
| | | | Also fixes a serious bug in xmlXPtrNewRangeNodePoint.
* Porting libxml2 on zOS encoding of codeStéphane Michaut2017-08-281-0/+5
| | | | | | | | | | First set of patches for zOS - entities.c parser.c tree.c xmlschemas.c xmlschemastypes.c xpath.c xpointer.c: ask conversion of code to ISO Latin 1 to avoid having the compiler assume EBCDIC codepoint for characters. - xmlmodule.c: make sure we have support for modules - xmlIO.c: zOS path names are special avoid dsome of the expectstions from Unix/Windows
* Fix memory leaks in XPointer error pathsNick Wellnhofer2017-05-271-1/+10
| | | | Found with libFuzzer and ASan.
* Fix more NULL pointer derefs in xpointer.cNick Wellnhofer2016-10-121-5/+7
| | | | Found with afl-fuzz.
* Disallow namespace nodes in XPointer rangesNick Wellnhofer2016-10-121-93/+56
| | | | | | | | | | Namespace nodes must be copied to avoid use-after-free errors. But they don't necessarily have a physical representation in a document, so simply disallow them in XPointer ranges. Found with afl-fuzz. Fixes CVE-2016-4658.
* Disallow namespace nodes in XPointer pointsNick Wellnhofer2016-10-121-4/+4
|
* Fix XPointer paths beginning with range-toNick Wellnhofer2016-10-121-70/+6
| | | | | | | | | | | | | The old code would invoke the broken xmlXPtrRangeToFunction. range-to isn't really a function but a special kind of location step. Remove this function and always handle range-to in the XPath code. The old xmlXPtrRangeToFunction could also be abused to trigger a use-after-free error with the potential for remote code execution. Found with afl-fuzz. Fixes CVE-2016-5131.
* Fix some format string warnings with possible format string vulnerabilityDavid Kilzer2016-05-231-1/+1
| | | | | | | | For https://bugzilla.gnome.org/show_bug.cgi?id=761029 Decorate every method in libxml2 with the appropriate LIBXML_ATTR_FORMAT(fmt,args) macro and add some cleanups following the reports.
* xpointer : fixing Null PointersGaurav Gupta2014-10-071-0/+28
| | | | | | For https://bugzilla.gnome.org/show_bug.cgi?id=738053 At many places in xpointer.c Null check is missing which is dereferenced at later places.
