Description

It looks like CVE-2009-1382 is not a problem because it is only in mimetex.cgi which isn't in kadu. But CVE-2009-2459 is still an issue. I'm not sure that it is. The report that generated the CVE contains this (which is what the CVE was based on): "In addition, the \environ, \input and \counter directives may be unsuitable for exposure to untrusted input from the internet and have therefore been disabled by default." Looking at kadu, the mime_text module allows for editing TeX math formulas in a chat. I suppose chatting with someone might be considered untrusted input, but you need to be chatting with the person first (and presumably trust them to some degree, or at least know them). I also don't believe there is a "mimetex library" that can be linked against. We could/should probably update kadu's mimetex source from the upstream mimetex sources, but upstream kadu should probably be informed as well. Have you reported this upstream? The kadu website asks to submit bugs to their forum. Their forum is in Polish however and translation is not being nice. Can the Fedora package maintainer submit a report upstream? I think you are right that there is not a library package of mimetex. I don't think there are other uses of embedded mimetex in Fedora, but I will do some more checking when I am back at my office tomorrow. I also consider unsolicited chat a reasonable attack vector, but it does require some user action. My main concern with this bug report is knowing for certain if the vulnerable code the CVE talks about is present in the kadu mimetex. Right, it does require user intervention, which lessens the impact. Hopefully the Fedora maintainer can report the issue upstream. Regardless, I do think it's something we would want to fix; regardless of the impact it is an issue. Removing security restriction, the issue is public. This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Bumping this to Fedora 14; it would be ideal to see this correct in F14+. This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping kadu 0.10.1 seems to be using mimetex 1.71: % egrep '^#define\s(VERSION|REVISION)' mimetex.c #define VERSION "1.71" /* mimeTeX version number */ #define REVISIONDATE "18 November 2009" /* date of most recent revision */ Unfortunately, it's only in Fedora 16 testing, not in Fedora 17 (failed build), or Fedora 18. This still needs to be fixed (getting 0.10.1 to build and pushed to all supported versions of Fedora would suffice).
