------------------------------------------------------------------------- Debian LTS Advisory DLA-3509-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Markus Koschany July 27, 2023 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : libmail-dkim-perl Version : 0.54-1+deb10u1 Debian Bug : 1039489 It was discovered that the domain check in libmail-dkim-perl, a Perl module to cryptographically identify the sender of email, compares i and d tags case sensitive when t=s is set on the DKIM key which causes spurious fails of legitimate messages. For Debian 10 buster, this problem has been fixed in version 0.54-1+deb10u1. We recommend that you upgrade your libmail-dkim-perl packages. For the detailed security status of libmail-dkim-perl please refer to its security tracker page at: https://security-tracker.debian.org/tracker/libmail-dkim-perl Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS
