An update of the pkg package has been released.

An update of the glib package has been released.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:4385 advisory.

  - An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with     G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also     creates the target of the symlink as an empty file, which could conceivably have security relevance if the     symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents     of that file correctly remain unchanged.) (CVE-2021-28153)

  - A flaw was found in glib before version 2.63.6. Due to random charset alias, pkexec can leak content from     files owned by privileged users to unprivileged ones under the right condition. (CVE-2021-3800)

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

The version of glib2 installed on the remote host is prior to 2.36.3-5.23. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1742 advisory.

    In GNOME GLib 2.56.1, g_markup_parse_context_end_parse() in gmarkup.c has a NULL pointer dereference.
    (CVE-2018-16428)

    GNOME GLib 2.56.1 has an out-of-bounds read vulnerability in g_markup_parse_context_parse() in gmarkup.c,     related to utf8_str(). (CVE-2018-16429)

    The keyfile settings backend in GNOME GLib (aka glib2.0) before 2.60.0 creates directories using     g_file_make_directory_with_parents (kfsb->dir, NULL, NULL) and files using g_file_replace_contents     (kfsb->file, contents, length, NULL, FALSE, G_FILE_CREATE_REPLACE_DESTINATION, NULL, NULL, NULL).
    Consequently, it does not properly restrict directory (and file) permissions. Instead, for directories,     0777 permissions are used; for files, default file permissions are used. This is similar to     CVE-2019-12450. (CVE-2019-13012)

    An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with     G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also     creates the target of the symlink as an empty file, which could conceivably have security relevance if the     symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents     of that file correctly remain unchanged.) (CVE-2021-28153)

    A flaw was found in glib before version 2.63.6. Due to random charset alias, pkexec can leak content from     files owned by privileged users to unprivileged ones under the right condition. (CVE-2021-3800)

    The upstream bug report describes this issue as follows:

    A vulnerability was found in GLib2.0, where DoS caused by handling a malicious text-form variant which is     structured to cause looping superlinear to its text size. Applications are at risk if they parse untrusted     text-form variants. (CVE-2023-24593)

The CentOS Linux 7.9 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_1646 advisory.

    This advisory aggregates security fixes for the glib2 SRPM in CIQ CentOS Bridge 7.9. It addresses 4 CVEs:
    CVE-2024-52533, CVE-2021-3800, CVE-2021-27218, CVE-2025-13601.

According to the versions of the glib2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in glib before version 2.63.6. Due to random charset alias, pkexec can leak content from     files owned by privileged users to unprivileged ones under the right condition. (CVE-2021-3800)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote NewStart CGSL host, running version MAIN 6.02, has glib2 packages installed that are affected by multiple vulnerabilities:

  - An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with     G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also     creates the target of the symlink as an empty file, which could conceivably have security relevance if the     symlink is attacker-controlled.

  - A flaw was found in glib before version 2.63.6. Due to random charset alias, pkexec can leak content from     files owned by privileged users to unprivileged ones under the right condition. (CVE-2021-3800)

  - An issue was discovered in GNOME GLib before 2.66.7 and 2.67.x before 2.67.4. If g_byte_array_new_take()     was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2**32,     causing unintended length truncation. (CVE-2021-27218)
