+Subject: [PATCH] XML::Bare: advance stuck attribute-name state (infinite loop)
+
+Infinite loop (CWE-835) in the hand-rolled C parser (parser.c), reached
+by the default XML::Bare->new(text=>$xml)->parse on untrusted XML.
+
+The `att_nameqsdone` state — reached after a single-quoted attribute
+*name* — loops back to itself without advancing `cpos` on any character
+other than `=` or NUL, spinning forever in C on malformed input. The
+parser holds the interpreter for the duration of the call, so no
+Perl-level signal (`alarm`, etc.) can interrupt it: a single request
+pins a CPU indefinitely. Triggers: `<a ='c'>`, `<a b='''''''c'>`,
+`<x y=''''''z'>`.
+
+Fix: advance the cursor before looping, so the scan terminates at the
+next `=` or at the NUL sentinel (already handled by the `case 0` branch).

+Subject: [PATCH] XML::Bare: bounds truncated fixed-advance lookahead (heap OOB read)
+
+Heap-buffer-overflow READ (CWE-125) in the hand-rolled C parser
+(parser.c), reached by the default XML::Bare->new(text=>$xml)->parse on
+untrusted XML.
+
+Several transitions advance `cpos` by a fixed amount past a recognised
+token without checking the buffer end, then dereference the new position:
+
+  - the `<![CDATA` match does `cpos += 9` after confirming only eight
+    bytes (`<![CDATA`), so a truncated tail such as `<![CDATA\0` steps
+    one byte past the NUL terminator;
+  - the three "self-closing tag" branches (name_x, name_gap, att_name)
+    do `cpos += 2` on the assumption that a `>` follows the `/`, so a
+    truncated tail such as `<a/\0` steps past the NUL.
+
+The subsequent `let = *cpos;` in val_1/val_x/cdata then reads out of
+bounds. Trigger: `<!-- c --><a/`.
+
+Fix: require the full `<![CDATA[` (nine bytes) before the `+= 9`, and
+only skip the assumed `>` when `*(cpos+1)` is non-NUL. Both changes are
+behaviour-preserving for well-formed input — real CDATA always carries
+the `[`, and a non-truncated self-close always has a byte after the `/`;
+they differ only on the truncated-tail case that previously overran the
+allocation.
