The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2021:0055 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-13012:
    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-2021-27218:
    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.

Tenable has extracted the preceding description block directly from the Alibaba Cloud 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.

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

  - PCRE 7.8 and 8.32 through 8.37, and PCRE2 10.10     mishandle group empty matches, which might allow remote     attackers to cause a denial of service (stack-based     buffer overflow) via a crafted regular expression, as     demonstrated by     /^(?:(?(1)\\.|([^\\\\W_])?)+)+$/.(CVE-2015-3217)

  - Heap-based buffer overflow in the find_fixedlength     function in pcre_compile.c in PCRE before 8.38 allows     remote attackers to cause a denial of service (crash)     or obtain sensitive information from heap memory and     possibly bypass the ASLR protection mechanism via a     crafted regular expression with an excess closing     parenthesis.(CVE-2015-5073)

  - 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)

  - file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0     through 2.61.1 does not properly restrict file     permissions while a copy operation is in progress.
    Instead, default permissions are used.(CVE-2019-12450)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4049-1 advisory.

    It was discovered that GLib created directories and files without properly restricting permissions. An     attacker could possibly use this issue to access sensitive information.

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

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

An update of the glib package has been released.

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

  - The keyfile settings backend in GNOME GLib (aka     glib2.0) before 2.60.0 creates directories using     g_file_make_directory_with_parents (kfsb-i1/4zdir, NULL,     NULL) and files using g_file_replace_contents     (kfsb-i1/4zfile, 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)

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2021:1586 advisory.

  - glib2: insecure permissions for files and directories (CVE-2019-13012)

  - webkitgtk: use-after-free may lead to arbitrary code execution (CVE-2020-13543, CVE-2020-13584,     CVE-2020-9951)

  - webkitgtk: type confusion may lead to arbitrary code execution (CVE-2020-9948)

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)
