I recently worked on the following RC bugs:
#696187 — squid-cgi: CVE-2012-5643: cachemgr.cgi denial of service
NMUed the upstream patches after nearly 2 months of no maintainer reaction on the bugreport.
#684645 — sendmail-bin: Order of fcntl and dotlock in maillock
Coordinated with the soon-to-be maintainer and explained (in private) that the upload should only contain a minimum amount of changes in order to be unblocked.
#690075 — unblock: dnsmasq/2.63-4
Pinged the maintainer about the current situation.
#693208 — clang: unable to link trivial test program on armhf
Reproduced the issue, now building clang on qemu-armhf… This takes quite a while.
It is getting hard to find RC bugs to work on. If you have access to ia64 hardware, have a look at #694971 — Epiphany browser crashes within JSC::JSArray::increaseVectorLength() or #697172 — sporadic crashes of epiphany browser due to a thread-unsafe favicon database. Both have patches available that just need to be tested.
