- -------------------------------------------------------------------------

Package : ruby-loofah Version : 2.2.3-1+deb10u2 CVE ID : CVE-2022-23514 CVE-2022-23515 CVE-2022-23516 Debian Bug : 1026083

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.
