Description John Eckersberg 2014-02-11 14:58:16 UTC
Original report from Debian:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=738587

===
The patch libyaml-indent-column-overflow-v2.patch applied for the
update to address CVE-2013-6393 introduces a regression which can be
seen when parsing a small YAML sample file with the tests/run-parser.c
utility:

----cut---------cut---------cut---------cut---------cut---------cut-----
%YAML 1.1
--- # Indented Block
  name: John Smith
  age: 33
--- # Inline Block
{name: John Smith, age: 33}
----cut---------cut---------cut---------cut---------cut---------cut-----

Compiling run-parser.c in the source and run against this YAML file
leads with the patch applied to:

# ./run-parser ./regression.yaml 
[1] Parsing './regression.yaml': FAILURE (9 events)

Upstream indeed has addressed this part slightly different, with [1]
and [2].
