TencentOS Server 4: nginx (TSSA-2024:0497)

high Nessus Plugin ID 239636

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 multiple vulnerabilities as referenced in the TSSA-2024:0497 advisory.

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

CVE-2024-34161:
When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed HTTP/3 requests can cause NGINX worker processes to terminate.

CVE-2024-31079:
When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module and the network infrastructure supports a Maximum Transmission Unit (MTU) of 4096 or greater without fragmentation, undisclosed QUIC packets can cause NGINX worker processes to leak previously freed memory.

CVE-2024-32760:
When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed HTTP/3 encoder instructions can cause NGINX worker processes to terminate or cause or other potential impact.

CVE-2024-35200:
When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed HTTP/3 requests can cause NGINX worker processes to terminate or causeother potential impact. This attack requires that a request be specifically timed during the connection draining process, which the attacker has no visibility and limited influence over.

CVE-2024-7347:
NGINX Open Source and NGINX Plus have a vulnerability in the ngx_http_mp4_module, which might allow an attacker to over-read NGINX worker memory resulting in its termination, using a specially crafted mp4 file. The issue only affects NGINX if it is built with the ngx_http_mp4_module and the mp4 directive is used in the configuration file. Additionally, the attack is possible only if an attacker can trigger the processing of a specially crafted mp4 file with the ngx_http_mp4_module. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

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

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

Solution

Update the affected packages.
