Debian DSA-5365-1 : curl - security update

medium Nessus Plugin ID 172027

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5365 advisory.

- An insufficiently protected credentials vulnerability exists in curl 4.9 to and include curl 7.82.0 are affected that could allow an attacker to extract credentials when follows HTTP(S) redirects is used with authentication could leak credentials to other services that exist on different protocols or port numbers.
(CVE-2022-27774)

- An allocation of resources without limits or throttling vulnerability exists in curl <v7.88.0 based on the chained HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with differentalgorithms. The number of acceptable links in this decompression chain wascapped, but the cap was implemented on a per-header basis allowing a maliciousserver to insert a virtually unlimited number of compression steps simply byusing many headers. The use of such a decompression chain could result in a malloc bomb, making curl end up spending enormous amounts of allocated heap memory, or trying to and returning out of memory errors. (CVE-2023-23916)

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

Solution

Upgrade the curl packages.

For the stable distribution (bullseye), this problem has been fixed in version 7.74.0-1.3+deb11u7.
