Bug#926986: www.debian.org: https://www.debian.org/security/dsa-long XML parsing failure

Package: www.debian.org
Severity: normal

For the past day or two, XML parsing on https://www.debian.org/security/dsa-long has been failing.
The issue seems to be caused by an incorrectly escaped ampersand in the description in a DSA.
The issue has not been present before, as there has not previously been an ampersand inside a description.

I would be willing to contribute a patch if necessary.

Thanks,
Frank Dai
