SUSE SLED15 / SLES15 / openSUSE 15 Security Update : libmicrohttpd (SUSE-SU-2023:1686-1)

medium Nessus Plugin ID 173687

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2023:1686-1 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

Update the affected libmicrohttpd-devel and / or libmicrohttpd12 packages.
