#Debian LTS contributors released 56 DLAs fixing 877 CVEs in May, a larger number than usual. The Kernel team deserves a special mention for handling the disclosed vulnerabilities on #linux regarding Local Privilege Escalation with public proof-of-concept exploits. On the LTS side, the Front Desk team also triaged a significant flow of high severity CVEs and notable security updates were released for exim, gnutls28, krb5, lemonldap-ng, imagemagick, openjdk-11, openjdk-17, php7.4, python3.9 and more.
Several patches were prepared by Catalyst for #Samba 4.17 shipped with Debian 12, to fix vulnerabilities disclosed in May, thanks to Freexian's partnership with them to extend the support.
LTS team also contributed with updates to the latest Debian releases, #bookworm and #trixie.
