TencentOS Server 2: squid (TSSA-2024:0116)

high Nessus Plugin ID 239411

Synopsis

The remote TencentOS Server 2 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0116 advisory.

Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

CVE-2023-46724:
A flaw was found in Squid. Due to an improper validation of the specified index bug, Squid compiled using `--with-openssl` is vulnerable to a denial of service attack against SSL Certificate validation. This flaw allows a remote server to perform a denial of service against the Squid Proxy by initiating a TLS Handshake with a specially crafted SSL Certificate in a server certificate chain. This attack is limited to HTTPS and SSL-Bump.

CVE-2023-46728:
Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to a NULL pointer dereference bug Squid is vulnerable to a Denial of Service attack against Squid's Gopher gateway. The gopher protocol is always available and enabled in Squid. This issue may lead to a remote denial of service via gopher URL requests.

CVE-2023-49285:
A buffer over-read flaw was found in Squid's HTTP Message processing feature. This issue may allow attackers to perform remote denial of service.

CVE-2023-49286:
A flaw was found in Squid due to an incorrect check of the return value in the helper process management.
This issue may allow attackers to perform remote denial of service.

CVE-2023-50269:
A flaw was found in Squid, which is susceptible to a Denial of Service (DoS) due to an Uncontrolled Recursion bug, specifically targeting HTTP Request parsing. Exploiting this issue involves a remote client initiating a DoS attack by sending an oversized X-Forwarded-For header when the follow_x_forwarded_for feature is configured. This issue poses a threat to the stability and availability of the Squid service.

CVE-2024-25617:
A flaw was found in Squid. This issue may allow a remote client or remote server to trigger a denial of service when sending oversized headers in HTTP messages.

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.
