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.
