dev-perl/HTML-Parser-3.63 is already in the tree.

Thanks. My understanding is that only perl-5.10.1 is affected by the crash issue. Can you confirm that our latest stable version of perl is not affected? If yes, we'll stabilize HTML-Parser-3.63 only; if no, we'll have to patch our latest stable perl as well.

[Comment 3 Tobias Heinlein (RETIRED) 2009-10-23 17:14:05 UTC]

I wonder if this is actually a security bug at all. Someone else from security, please advise.

Yes, no segfault with 5.8.8 and the test script from rt69973.
perl-5.10.1 is fixed too.

CVE-2009-3627 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3627):
  The decode_entities function in util.c in HTML-Parser before 3.63
  allows context-dependent attackers to cause a denial of service
  (infinite loop) via an incomplete SGML numeric character reference,
  which triggers generation of an invalid UTF-8 character.

*** Bug 293128 has been marked as a duplicate of this bug. ***

[Comment 8 Robert Buchholz (RETIRED) 2009-11-16 12:30:14 UTC]

This is a bug in stable HTML-Parser that triggers a vulnerability in unstable Perl. Since the bug in Perl is being fixed (bug 293128), there is nothing to do on this bug for security.
As a precautionary measure I am adding architectures to stable the latest HTML-Parser release via this bug.

[Comment 9 Robert Buchholz (RETIRED) 2009-11-16 12:40:23 UTC]

Arches, please test and mark stable:
=dev-perl/HTML-Parser-3.64
Target keywords : "alpha amd64 arm hppa ia64 m68k ppc ppc64 s390 sh sparc x86"

[Comment 10 Jeroen Roovers (RETIRED) 2009-11-16 19:49:36 UTC]

Stable for HPPA.

[Comment 11 Markus Meier 2009-11-16 23:01:48 UTC]

Latest HTML-Parser is stable for all arches, the old versions were removed. I am closing this bug now.

[Comment 17 Tobias Heinlein (RETIRED) 2010-04-30 17:45:02 UTC]

This security bug was accidentally closed a while ago.

I vote NO.

[Comment 18 Stefan Behte (RETIRED) 2010-05-22 11:16:06 UTC]

No, too. Closing noglsa.
