Debian 10833 Published by

Several Debian security advisories have been released to address critical flaws in SPIP and evolution-data-server among other packages. The website engine suffers from a privilege escalation vulnerability while the database backend allows Flatpak apps to delete arbitrary host files. Web developers must patch path traversal issues within Ruby interfaces alongside denial of service risks found in Perl modules like libyaml-syck-perl.

ELA-1660-1 evolution-data-server security update


Package : evolution-data-server
Version : 3.22.7-1+deb9u3 (stretch), 3.30.5-1+deb10u3 (buster)

CVE-2026-2604

An issue has been found in evolution-data-server, an evolution database backend server. A Flatpak application with D-Bus access to the addressbook service can delete arbitrary files on the host, potentially including Flatpak override files. This fix canonicalizes the file path before performing a prefix comparison, ensuring that ../ sequences are resolved.

[SECURITY] [DLA 4505-1] ruby-rack security update

Debian LTS Advisory DLA-4505-1 debian-lts@lists.debian.org

Package : ruby-rack
Version : 2.1.4-3+deb11u5
CVE ID : CVE-2026-22860 CVE-2026-25500
Debian Bug : 1128479 1128480

Two vulnerabilities were discovered in ruby-rack, a modular Ruby
webserver interface.

CVE-2026-22860

Rack::Directory's path check used a string prefix match on the
expanded path. A request like /../root_example/ could escape the
configured root if the target path started with the root string,
allowing directory listing outside the intended root.

CVE-2026-25500

Rack::Directory generated an HTML directory index where each file
entry was rendered as a clickable link. If a file existed on disk
whose basename started with the javascript: scheme, the generated
index contained an anchor whose href executed JavaScript in the
browser, resulting in a stored XSS vulnerability.

For Debian 11 bullseye, these problems have been fixed in version
2.1.4-3+deb11u5.

We recommend that you upgrade your ruby-rack packages.

its security tracker page at:

Package : libyaml-syck-perl
CVE ID : CVE-2026-4177

Several vulnerabilities were discovered in libyaml-syck-perl, a Perl
module providing a fast, lightweight YAML loader and dumper, which may
result in denial of service and potentially arbitrary code execution.

For the oldstable distribution (bookworm), this problem has been fixed
in version 1.34-2+deb12u2.

For the stable distribution (trixie), this problem has been fixed in
version 1.34-2+deb13u2.
