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-2024:0039 advisory.

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

    CVE-2023-46724:
    Squid is a caching proxy for the Web. Due to an Improper Validation of Specified Index bug, Squid versions     3.3.0.1 through 5.9 and 6.0 prior to 6.4 compiled using `--with-openssl` are vulnerable to a Denial of     Service attack against SSL Certificate validation. This problem allows a remote server to perform Denial     of Service against 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. This bug is fixed in Squid version     6.4. In addition, patches addressing this problem for the stable releases can be found in Squid's patch     archives. Those who you use a prepackaged version of Squid should refer to the package vendor for     availability information on updated packages.

    CVE-2023-46846:
    SQUID is vulnerable to HTTP request smuggling, caused by chunked decoder lenience, allows a remote     attacker to perform Request/Response smuggling past firewall and frontend security systems.

    CVE-2023-46847:
    Squid is vulnerable to a Denial of Service,  where a remote attacker can perform buffer overflow attack by     writing up to 2 MB of arbitrary data to heap memory when Squid is configured to accept HTTP Digest     Authentication.

    CVE-2023-46848:
    Squid is vulnerable to Denial of Service,  where a remote attacker can perform DoS by sending ftp:// URLs     in HTTP Request messages or constructing ftp:// URLs from FTP Native input.

    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 prior to Squid 6.0.1. Responses triggering this     bug are possible to be received from any gopher server, even those without malicious intent. Gopher     support has been removed in Squid version 6.0.1. Users are advised to upgrade. Users unable to upgrade     should reject all gopher URL requests.

    CVE-2023-5824:
    Squid is vulnerable to Denial of Service attack against HTTP and HTTPS clients due to an Improper Handling     of Structural Elements bug.

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

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1787 advisory.

  - Squid is a caching proxy for the Web. Due to an Improper Validation of Specified Index bug, Squid versions     3.3.0.1 through 5.9 and 6.0 prior to 6.4 compiled using `--with-openssl` are vulnerable to a Denial of     Service attack against SSL Certificate validation.

    (CVE-2023-49285)

  - Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to an Incorrect Check of     Function Return Value bug Squid is vulnerable to a Denial of Service attack against its Helper process     management. This bug is fixed by Squid version 6.5. Users are advised to upgrade. There are no known     workarounds for this vulnerability. (CVE-2023-49286)

  - Squid is a caching proxy for the Web. Due to an Uncontrolled Recursion bug in versions 2.6 through     2.7.STABLE9, versions 3.1 through 5.9, and versions 6.0.1 through 6.5, Squid may be vulnerable to a Denial     of Service attack against HTTP Request parsing. This problem allows a remote client to perform Denial of     Service attack by sending a large X-Forwarded-For header when the follow_x_forwarded_for feature is     configured. This bug is fixed by Squid version 6.6. In addition, patches addressing this problem for the     stable releases can be found in Squid's patch archives. (CVE-2023-50269)

  - Squid is an open source caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to a Collapse     of Data into Unsafe Value bug ,Squid may be vulnerable to a Denial of Service attack against HTTP header     parsing. This problem allows a remote client or a remote server to perform Denial of Service when sending     oversized headers in HTTP messages. In versions of Squid prior to 6.5 this can be achieved if the     request_header_max_size or reply_header_max_size settings are unchanged from the default. In Squid version     6.5 and later, the default setting of these parameters is safe. Squid will emit a critical warning in     cache.log if the administrator is setting these parameters to unsafe values. Squid will not at this time     prevent these settings from being changed to unsafe values. Users are advised to upgrade to version 6.5.
    There are no known workarounds for this vulnerability. This issue is also tracked as SQUID-2024:2     (CVE-2024-25617)
