Description Tim Sammut (RETIRED) gentoo-dev 2010-08-20 15:41:55 UTC
From $url:

When HX_split is called with a maximum number of desired fields (4th
argument != 0), passing in a string that has less fields than that led
to a buffer overrun (write beyond end of malloc'd area).

CVSS Base Score: 10
- Impact Subscore: 10
- Exploitability Subscore: 10

CVSS Temporal Score: 7.4
CVSS Environmental Score: Undefined

Overall CVSS Score: 7.4

CVSS Base vector:: AV:N/AC:L/Au:N/C:C/I:C/A:C
- AV: libHX may be used by network services
- Au: some services may not require authentication
- A: can cause crash when result is freed

CVSS Temporal vectors:: RL:O/RC:C

Affects all versions prior to, and including, 3.5.

Fixing whiteboard and severity based on CVSS vector of:

AV:N/AC:L/Au:N/C:C/I:C/A:C

Thanks for the tip, Craig.
Comment 8 Tim Sammut (RETIRED) gentoo-dev 2010-10-01 04:18:35 UTC
GLSA request filed.
Comment 9 Matt Turner gentoo-dev 2011-05-14 20:30:29 UTC
libhx-3.5 is stabilized everywhere it has keywords, and all versions below 3.5 have been dropped. Is there anything else that needs to be done?

> Is there anything else that needs to be done?

Hi, Matt. We need to publish a GLSA for this one (and any other open bugs with [glsa] in the whiteboard). Once that happens, we'll close the bug.
Comment 11 Matt Turner gentoo-dev 2013-10-05 01:15:43 UTC
Can you go ahead and vote that you're not going to do anything?
