+Release 2.4.6 Sun February 20 2022

+ Bug fixes:

+ #566 Fix a regression introduced by the fix for CVE-2022-25313

+ in release 2.4.5 that affects applications that (1)

+ call function XML_SetElementDeclHandler and (2) are

+ parsing XML that contains nested element declarations

+ (e.g. "<!ELEMENT junk ((bar|foo|xyz+), zebra*)>").

+ Other changes:

+ #567 #568 Version info bumped from 9:5:8 to 9:6:8;

+ see https://verbump.de/ for what these numbers do

+ Special thanks to:

+ Matt Sergeant

+ Samanta Navarro

+ Sergei Trofimovich

+ and

+ NixOS

+ Perl XML::Parser

+Release 2.4.5 Fri February 18 2022

+ Security fixes:

+ #562 CVE-2022-25235 -- Passing malformed 2- and 3-byte UTF-8

+ sequences (e.g. from start tag names) to the XML

+ processing application on top of Expat can cause

+ arbitrary damage (e.g. code execution) depending

+ on how invalid UTF-8 is handled inside the XML

+ processor; validation was not their job but Expat's.

+ Exploits with code execution are known to exist.

+ #561 CVE-2022-25236 -- Passing (one or more) namespace separator

+ characters in "xmlns[:prefix]" attribute values

+ made Expat send malformed tag names to the XML

+ processor on top of Expat which can cause

+ arbitrary damage (e.g. code execution) depending

+ on such unexpectable cases are handled inside the XML

+ processor; validation was not their job but Expat's.

+ Exploits with code execution are known to exist.

+ #558 CVE-2022-25313 -- Fix stack exhaustion in doctype parsing

+ that could be triggered by e.g. a 2 megabytes

+ file with a large number of opening braces.

+ Expected impact is denial of service or potentially

+ arbitrary code execution.

+ #560 CVE-2022-25314 -- Fix integer overflow in function copyString;

+ only affects the encoding name parameter at parser creation

+ time which is often hardcoded (rather than user input),

+ takes a value in the gigabytes to trigger, and a 64-bit

+ machine. Expected impact is denial of service.

+ #559 CVE-2022-25315 -- Fix integer overflow in function storeRawNames;

+ needs input in the gigabytes and a 64-bit machine.

+ Expected impact is denial of service or potentially

+ arbitrary code execution.

+ Other changes:

+ #557 #564 Version info bumped from 9:4:8 to 9:5:8;

+ see https://verbump.de/ for what these numbers do

+ Special thanks to:

+ Ivan Fratric

+ Samanta Navarro

+ and

+ Google Project Zero

+ JetBrains

+Release 2.4.4 Sun January 30 2022

+ Security fixes:

+ #550 CVE-2022-23852 -- Fix signed integer overflow

+ (undefined behavior) in function XML_GetBuffer

+ (that is also called by function XML_Parse internally)

+ for when XML_CONTEXT_BYTES is defined to >0 (which is both

+ common and default).

+ Impact is denial of service or more.

+ #551 CVE-2022-23990 -- Fix unsigned integer overflow in function

+ doProlog triggered by large content in element type

+ declarations when there is an element declaration handler

+ present (from a prior call to XML_SetElementDeclHandler).

+ Impact is denial of service or more.

+ Bug fixes:

+ #544 #545 xmlwf: Fix a memory leak on output file opening error

+ Other changes:

+ #546 Autotools: Fix broken CMake support under Cygwin

+ #554 Windows: Add missing files to the installer to fix

+ compilation with CMake from installed sources

+ #552 #554 Version info bumped from 9:3:8 to 9:4:8;

+ * stack is avoided now by resolving recursion.)

+ *

+ * The iterative approach works as follows:

+ *

+ * - We have two writing pointers, both walking up the result array; one does

+ * the work, the other creates "jobs" for its colleague to do, and leads

+ * the way:

+ *

+ * - The faster one, pointer jobDest, always leads and writes "what job

+ * to do" by the other, once they reach that place in the

+ * array: leader "jobDest" stores the source node array index (relative

+ * to array dtd->scaffold) in field "numchildren".

+ *

+ * - The slower one, pointer dest, looks at the value stored in the

+ * "numchildren" field (which actually holds a source node array index

+ * at that time) and puts the real data from dtd->scaffold in.

+ *

+ * - Before the loop starts, jobDest writes source array index 0

+ * (where the root node is located) so that dest will have something to do

+ * when it starts operation.

+ *

+ * - Whenever nodes with children are encountered, jobDest appends

+ * them as new jobs, in order. As a result, tree node siblings are

+ * adjacent in the resulting array, for example:

+ *

+ * [0] root, has two children
