TencentOS Server 4: libmicrohttpd (TSSA-2025:0139)

high Nessus Plugin ID 238848

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:0139 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2023-27371:
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.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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 packages.
