Debian Security Advisory DSA-4171-1 security@debian.org
https://www.debian.org/security/ Salvatore Bonaccorso
April 13, 2018 https://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : ruby-loofah
CVE ID : CVE-2018-8048
Debian Bug : 893596
The Shopify Application Security Team reported that ruby-loofah, a
general library for manipulating and transforming HTML/XML documents and
fragments, allows non-whitelisted attributes to be present in sanitized
output when input with specially-crafted HTML fragments. This might
allow to mount a code injection attack into a browser consuming
sanitized output.
For the stable distribution (stretch), this problem has been fixed in
version 2.0.3-2+deb9u1.
We recommend that you upgrade your ruby-loofah packages.
For the detailed security status of ruby-loofah please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/ruby-loofah
