Debian DSA-5040-1 : lighttpd - security update

medium Nessus Plugin ID 156651

Language:

Synopsis

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

Description

The remote Debian 10 / 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-5040 advisory.

 - In lighttpd 1.4.46 through 1.4.63, the mod_extforward_Forwarded function of the mod_extforward plugin has a stack-based buffer overflow (4 bytes representing -1), as demonstrated by remote denial of service (daemon crash) in a non-default configuration. The non-default configuration requires handling of the Forwarded header in a somewhat unusual manner. Also, a 32-bit system is much more likely to be affected than a 64-bit system. (CVE-2022-22707)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the lighttpd packages.

For the stable distribution (bullseye), this problem has been fixed in version 1.4.59-1+deb11u1.
