Ah, I see.

Yeah, two problems with that: 1. according to the Debian Security Team,
CVE policies disallow merging of issues with significantly different
discovery times; 2. Mitre declined allocating a CVE even for the first
one, saying that the Apache Foundation should assign these for its own
products, or even more, it should have allocated one already during the
patching process.  Now, the Apache Security Team webpage emphasises that
they only handle undisclosed issues, so I'm uncertain what to do.  Are
you okay with me asking them nevertheless?

Also, SANTUARIO-496 affects 2.0.0+ only, but the same code is present in
earlier versions as well.  Is there really an excuse for not backporting
the fix to 1.7 as shipped (and patched for SANTUARIO-491) in Debian
stable, or you simply didn't care to enumerate such ancient versions?
