Debian DLA-3127-1 : libhttp-daemon-perl - LTS security update

medium Nessus Plugin ID 165685

Language:

Synopsis

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

Description

The remote Debian 10 host has a package installed that is affected by a vulnerability as referenced in the dla-3127 advisory.

- HTTP::Daemon is a simple http server class written in perl. Versions prior to 6.15 are subject to a vulnerability which could potentially be exploited to gain privileged access to APIs or poison intermediate caches. It is uncertain how large the risks are, most Perl based applications are served on top of Nginx or Apache, not on the `HTTP::Daemon`. This library is commonly used for local development and tests. Users are advised to update to resolve this issue. Users unable to upgrade may add additional request handling logic as a mitigation. After calling `my $rqst = $conn->get_request()` one could inspect the returned `HTTP::Request` object. Querying the 'Content-Length' (`my $cl = $rqst->header('Content- Length')`) will show any abnormalities that should be dealt with by a `400` response. Expected strings of 'Content-Length' SHOULD consist of either a single non-negative integer, or, a comma separated repetition of that number. (that is `42` or `42, 42, 42`). Anything else MUST be rejected. (CVE-2022-31081)

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 libhttp-daemon-perl packages.

For Debian 10 buster, this problem has been fixed in version 6.01-3+deb10u1.
