Debian DSA-3913-1 : apache2 - security update

critical Nessus Plugin ID 101793
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


Robert Swiecki reported that mod_auth_digest does not properly initialize or reset the value placeholder in [Proxy-]Authorization headers of type 'Digest' between successive key=value assignments, leading to information disclosure or denial of service.


Upgrade the apache2 packages.

For the oldstable distribution (jessie), this problem has been fixed in version 2.4.10-10+deb8u10.

For the stable distribution (stretch), this problem has been fixed in version 2.4.25-3+deb9u2.
