Description Jan Lieskovsky 2012-08-07 11:24:48 EDT
Multiple heap-based buffer overflow flaws were found in the way the Base64 decoder of libotr, an Off-The-Record Messaging library and toolkit, performed decoding of certain messages. A remote attacker could provide a specially-crafted OTR message that once processed in an application linked against libotr would lead to that application crash or, potentially, arbitrary code execution with the privileges of the user running the application.

Comment 3 Paul Wouters 2012-08-07 16:09:57 EDT
I'm talking with upstream. They only released a patch, which also increases the version number of the release, without releasing a tar ball. I'm trying to convince them to do a proper tar ball release.
Comment 4 Paul Wouters 2012-08-08 12:53:44 EDT
bodhi didn't update bugzilla, but Fedora builds have been made. EL builds will follow soon. https://admin.fedoraproject.org/updates/libotr-3.2.0-7.fc16 https://admin.fedoraproject.org/updates/libotr-3.2.0-8.fc17
Comment 5 Jan Lieskovsky 2012-08-08 13:32:57 EDT

https://admin.fedoraproject.org/updates/libotr-3.2.0-5.el6 https://admin.fedoraproject.org/updates/libotr-3.2.0-2.el5 (apparently security marked bugs get their announcements delayed on purpose)
Comment 8 Paul Wouters 2012-08-14 21:44:12 EDT
there is updated version of this patch, which is included in a new version of libotr (and pidgin-otr), despite earlier plans of upstream to not release a new version, I'm building this now and tomorrow
Comment 9 Paul Wouters 2012-08-16 14:59:08 EDT
builds are in testing. note there is no new CVE planned for the difference between the two patches.
