Package: libapache2-mpm-itk Version: 2.4.7-04-1+b1 Severity: important Dear Maintainer,
After installing the 2.4.51-1~deb11u1 security update the error log starts to get flilled with lines like: [core:notice] [pid 3115298] AH00052: child pid 3133160 exit signal Segmentation fault (11) Downgrading back to 2.4.48-3.1 made the errors disappear again. Disabling mpm_itk on 2.4.51-1~deb11u1 also stops the errors. The issue normally does not prevent pages from being loaded and they are still assigned the correct uid/gid. The problematic part lies in that it seems to cause issues with properly closing the connections. This lead to mod_qos limits being hit in my case, but I suspect it may also lead to hitting worker or thread pool limits in other cases. -- System Information: Debian Release: 11.0 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-8-amd64 (SMP w/24 CPU threads) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libapache2-mpm-itk depends on: ii apache2-bin [apache2-api-20120211] 2.4.48-3.1 ii libc6 2.31-13 ii libcap2 1:2.44-1 libapache2-mpm-itk recommends no packages. libapache2-mpm-itk suggests no packages. -- no debconf information
