The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0560 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2025-25186:
    Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Starting in     version 0.3.2 and prior to versions 0.3.8, 0.4.19, and 0.5.6, there is a possibility for denial of service     by memory exhaustion in net-imap's response parser.  At any time while the client is connected, a     malicious server can send  can send highly compressed uid-set data which is automatically read by the     client's receiver thread. The response parser uses Range#to_a to convert the uid-set data into arrays of     integers, with no limitation on the expanded size of the ranges. Versions 0.3.8, 0.4.19, 0.5.6, and higher     fix this issue. Additional details for proper configuration of fixed versions and backward compatibility     are available in the GitHub Security Advisory.

    CVE-2025-27219:
    In the CGI gem before 0.4.2 for Ruby, the CGI::Cookie.parse method in the CGI library contains a potential     Denial of Service (DoS) vulnerability. The method does not impose any limit on the length of the raw     cookie value it processes. This oversight can lead to excessive resource consumption when parsing     extremely large cookies.

    CVE-2025-27221:
    In the URI gem before 1.0.3 for Ruby, the URI handling methods (URI.join, URI#merge, URI#+) have an     inadvertent leakage of authentication credentials because userinfo is retained even after changing the     host.

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7418-1 advisory.

    It was discovered that Ruby incorrectly handled parsing of an XML document that has specific XML     characters in an attribute value using REXML gem. An attacker could use this issue to cause Ruby to crash,     resulting in a denial of service. This issue only affected in Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and     Ubuntu 24.10. (CVE-2024-35176, CVE-2024-39908, CVE-2024-41123, CVE-2024-43398)

    It was discovered that Ruby incorrectly handled expanding ranges in the net-imap response parser. If a     user or automated system were tricked into connecting to a malicious IMAP server, a remote attacker could     possibly use this issue to consume memory, leading to a denial of service. This issue only affected Ubuntu     24.04 LTS, and Ubuntu 24.10. (CVE-2025-25186)

    It was discovered that the Ruby CGI gem incorrectly handled parsing certain cookies. A remote attacker     could possibly use this issue to consume resources, leading to a denial of service. (CVE-2025-27219)

    It was discovered that the Ruby CGI gem incorrectly handled parsing certain regular expressions. A remote     attacker could possibly use this issue to consume resources, leading to a denial of service.
    (CVE-2025-27220)

    It was discovered that the Ruby URI gem incorrectly handled certain URI handling methods. A remote     attacker could possibly use this issue to leak authentication credentials. (CVE-2025-27221)

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-2025:0467 advisory.

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

    CVE-2025-43857:
    Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to     versions 0.5.7, 0.4.20, 0.3.9, and 0.2.5, there is a possibility for denial of service by memory     exhaustion when net-imap reads server responses. At any time while the client is connected, a malicious     server can send can send a literal byte count, which is automatically read by the client's receiver     thread. The response reader immediately allocates memory for the number of bytes indicated by the server     response. This should not be an issue when securely connecting to trusted IMAP servers that are well-     behaved. It can affect insecure connections and buggy, untrusted, or compromised servers (for example,     connecting to a user supplied hostname). This issue has been patched in versions 0.5.7, 0.4.20, 0.3.9, and     0.2.5.
