Source: glibc Version: 2.29-1 Severity: important User: debian-al...@lists.debian.org Usertags: alpha
Hello! Both on my Alpha XP-1000 as well as inside a qemu-user chroot, upgrading glibc to version 2.29-1 resulted in setuid/getuid breaking in a weird way: (sid-alpha-sbuild)root@epyc:/# apt -y upgrade Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade...
