From d4bf0799b80d8bbd128e9e41624779d844033a42 Mon Sep 17 00:00:00 2001 From: Nikita Popov Date: Thu, 22 Oct 2020 16:04:22 +0200 Subject: Don't crash on uninitialized tidy object "Uninitialized" here means that the object was created ordinarily -- no constructor skipping involved. Most tidy methods seem to handle this fine, but these three need to be guarded. --- ext/tidy/tests/uninitialized.phpt | 29 +++++++++++++++++++++++++++++ ext/tidy/tidy.c | 13 ++++++++++--- 2 files changed, 39 insertions(+), 3 deletions(-) create mode 100644 ext/tidy/tests/uninitialized.phpt diff --git a/ext/tidy/tests/uninitialized.phpt b/ext/tidy/tests/uninitialized.phpt new file mode 100644 index 0000000000..3533f0d345 --- /dev/null +++ b/ext/tidy/tests/uninitialized.phpt @@ -0,0 +1,29 @@ +--TEST-- +Operations on uninitialized tidy object +--SKIPIF-- + +--FILE-- +getHtmlVer()); +} catch (Error $e) { + echo $e->getMessage(), "\n"; +} +try { + var_dump($tidy->isXhtml()); +} catch (Error $e) { + echo $e->getMessage(), "\n"; +} +try { + var_dump($tidy->isXml()); +} catch (Error $e) { + echo $e->getMessage(), "\n"; +} + +?> +--EXPECT-- +tidy object is not initialized +tidy object is not initialized +tidy object is not initialized diff --git a/ext/tidy/tidy.c b/ext/tidy/tidy.c index 60170585ce..34fe525a1e 100644 --- a/ext/tidy/tidy.c +++ b/ext/tidy/tidy.c @@ -66,6 +66,13 @@ } \ obj = Z_TIDY_P(object); \ +#define TIDY_FETCH_INITIALIZED_OBJECT \ + TIDY_FETCH_OBJECT; \ + if (!obj->ptdoc->initialized) { \ + zend_throw_error(NULL, "tidy object is not initialized"); \ + return; \ + } + #define TIDY_FETCH_ONLY_OBJECT \ PHPTidyObj *obj; \ TIDY_SET_CONTEXT; \ @@ -1474,7 +1481,7 @@ static PHP_FUNCTION(tidy_get_status) Get the Detected HTML version for the specified document. */ static PHP_FUNCTION(tidy_get_html_ver) { - TIDY_FETCH_OBJECT; + TIDY_FETCH_INITIALIZED_OBJECT; RETURN_LONG(tidyDetectedHtmlVersion(obj->ptdoc->doc)); } @@ -1484,7 +1491,7 @@ static PHP_FUNCTION(tidy_get_html_ver) Indicates if the document is a XHTML document. */ static PHP_FUNCTION(tidy_is_xhtml) { - TIDY_FETCH_OBJECT; + TIDY_FETCH_INITIALIZED_OBJECT; RETURN_BOOL(tidyDetectedXhtml(obj->ptdoc->doc)); } @@ -1494,7 +1501,7 @@ static PHP_FUNCTION(tidy_is_xhtml) Indicates if the document is a generic (non HTML/XHTML) XML document. */ static PHP_FUNCTION(tidy_is_xml) { - TIDY_FETCH_OBJECT; + TIDY_FETCH_INITIALIZED_OBJECT; RETURN_BOOL(tidyDetectedGenericXml(obj->ptdoc->doc)); } -- cgit v1.2.1
