Re: CVE Request -- gallery3 (3.0.9): Fixing two security flaws

Hello everyone, A quick clarification on issue #2: the problem wasn't the item information or paths, but rather the original-sized image file. A legitimate user with "view" privileges for an item should be able to: - get the item info and image file links (e.g. ".../rest/data/123?size=thumb", etc.) - follow the links and get the "thumb" and "resize" image files themselves. - guess the "full" image file link without thinking too hard (e.g. ".../rest/data/123?size=full") - follow the link and get the "full" image file itself **ONLY** if they have "view_full" access. The problem was that this last condition wasn't being properly enforced. Thanks again, and sorry for the delay in response! Shad On 4 July 2013 11:19, Jan Lieskovsky <jlieskov () redhat com> wrote:
Hello Kurt, Steve, vendors, Gallery upstream has released 3.0.9 version, correcting two security flaws: [1] http://galleryproject.org/gallery_3_0_9 My guess [***] is the two issues are as follows: * Issue #1 - Improper stripping of URL fragments in flowplayer SWF file might lead to reply attacks (a different flaw than CVE-2013-2138): ---------------------------------------------------------------------------- A security flaw was found in the way flowplayer SWF file handling functionality of Gallery version 3, an open source project with the goal to develop and support leading photo sharing web application solutions, processed certain URL fragments passed to this file (certain URL fragments were not stripped properly when these files were called via direct URL request(s)). A remote attacker could use this flaw to conduct replay attacks. A different vulnerability than CVE-2013-2138. Upstream ticket: [2] http://sourceforge.net/apps/trac/gallery/ticket/2073 Relevant upstream patch: [3] https://github.com/gallery/gallery3/commit/c5318bb1a2dd266b50317a2adb74d74338593733 References: [4] https://bugzilla.redhat.com/show_bug.cgi?id=981197 * Issue #2 - gallery3: Multiple information exposure flaws in data rest core module ----------------------------------------------------------------------------------- Multiple information exposure flaws were found in the way data rest core module of Gallery version 3, an open source project with the goal to develop and support leading photo sharing web application solutions, used to previously restrict access to certain items of the photo album. A remote attacker, valid Gallery 3 user, could use this flaw to possibly obtain sensitive information (file, resize or thumb path of the item in question). Upstream ticket: [5] http://sourceforge.net/apps/trac/gallery/ticket/2074 Relevant upstream patch (against 3.0.x branch): [6] https://github.com/gallery/gallery3/commit/cbbcf1b4791762d7da0ea7b6c4f4b551a4d9caed References: [7] https://bugzilla.redhat.com/show_bug.cgi?id=981198 Could you allocate CVE identifiers for these? Thank you && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team [***] Guess because the issues aren't more thoroughly described in upstream announcement [1] and former (private) email check with Gallery3 upstream didn't provide more details either. Cc-ed them on this post too, they to correct me where necessary.
