- ------------------------------------------------------------------------- Debian LTS Advisory DLA-4018-2 [email protected] https://www.debian.org/lts/security/ Bastien Roucaris February 11, 2025 https://wiki.debian.org/LTS
- -------------------------------------------------------------------------

Package : ruby2.7 Version : 2.7.4-1+deb11u4

A regression was identified in rexml gem.

A corner case of XML namespace default namespace was not handled correctly, and thus rexml failed to parse valid XML file.

For Debian 11 bullseye, this problem has been fixed in version 2.7.4-1+deb11u4.

We recommend that you upgrade your ruby2.7 packages.

For the detailed security status of ruby2.7 please refer to its security tracker page at:
