Debian DLA-3374-1 : libmicrohttpd - LTS security update

medium Nessus Plugin ID 173791

Language:

Synopsis

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

Description

The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3374 advisory.

 - GNU libmicrohttpd before 0.9.76 allows remote DoS (Denial of Service) due to improper parsing of a multipart/form-data boundary in the postprocessor.c MHD_create_post_processor() method. This allows an attacker to remotely send a malicious HTTP POST packet that includes one or more '\0' bytes in a multipart/form-data boundary field, which - assuming a specific heap layout - will result in an out-of- bounds read and a crash in the find_boundary() function. (CVE-2023-27371)

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 libmicrohttpd packages.

For Debian 10 buster, this problem has been fixed in version 0.9.62-1+deb10u1.
