This can be exploited to cause a heap-based buffer overflow via certain specially crafted regular expressions. The vulnerability is reported in version 3.8.1. Other versions may also be affected. Solution: Apply patch. http://source.icu-project.org/repos/icu/icu/branches/maint/maint-3-8 Reply at: https://bugs.launchpad.net/ubuntu/+source/icu/+bug/186578/comments/9 ------------------------------------------------------------------------ On 2008-01-29T07:37:00+00:00 lars wrote: maintainers - please provide an updated ebuild Reply at: https://bugs.launchpad.net/ubuntu/+source/icu/+bug/186578/comments/10 ------------------------------------------------------------------------ On 2008-01-29T08:17:50+00:00 jakub wrote: *** Bug 207905 has been marked as a duplicate of this bug. *** Reply at: https://bugs.launchpad.net/ubuntu/+source/icu/+bug/186578/comments/11 ------------------------------------------------------------------------ On 2008-02-01T22:51:47+00:00 rbu wrote: ping Reply at: https://bugs.launchpad.net/ubuntu/+source/icu/+bug/186578/comments/12 ------------------------------------------------------------------------ On 2008-02-01T23:35:32+00:00 rbu wrote: I reproduced the 4771 issue on 3.6.1. Caolan McNamara from RedHat backported the patches to 3.6: https://bugzilla.redhat.com/show_bug.cgi?id=429023 This bug also affects OpenOffice, as it currently uses an internal copy of icu. OpenOffice herd, please advise here.

I did not do any tests except from compiling (I haven't touched that package before anyway). I might try building OOo tomorrow, but certainly not today.

It won't compile with ~icu-3.6. arches, please test and stabilize the following: dev-libs/icu-3.6-r2 (will be hanging around for dev-libs/xerces-c-2.8.0 at least unless someone fixes the messy thing to work w/ icu-3.8.x) dev-libs/icu-3.8.1-r1 Reply at: https://bugs.launchpad.net/ubuntu/+source/icu/+bug/186578/comments/18 ------------------------------------------------------------------------ On 2008-02-03T18:51:14+00:00 ranger wrote: ppc and ppc64 done. dertobi123 tested ppc and I committed for his convenience.
