## Notes

### [jdstrand](https://launchpad.net/~jdstrand)

Reducing priority because we build with -D\_FORTIFY\_SOURCE=2 and
as of USN-1396-1, Ubuntu's glibc is patched to fix (CVE-2012-0864), so this
is reduced to a denial of service.
per upstream, only 1.10 and higher are affected:

to crash in natty and oneiric, marking those not-affected
