Details

Multiple vulnerabilities were discovered in Loofah, a Ruby library for HTML/XML transformation and sanitization. An attacker could launch cross-site scripting (XSS) and denial-of-service (DoS) attacks through crafted HTML/XML documents.

• CVE-2022-23514 Inefficient regular expression that is susceptible to excessive backtracking when attempting to sanitize certain SVG attributes. This may lead to a denial of service through CPU resource consumption.
• CVE-2022-23515 Cross-site scripting via the image/svg+xml media type in data URIs.
• CVE-2022-23516 Loofah uses recursion for sanitizing CDATA sections, making it susceptible to stack exhaustion and raising a SystemStackError exception. This may lead to a denial of service through CPU resource consumption.

For Debian 10 buster, these problems have been fixed in version 2.2.3-1+deb10u2.

We recommend that you upgrade your ruby-loofah packages.
