This update for glib2 fixes the following issues :

Security issue fixed :

CVE-2019-13012: Fixed improper restriction of file permissions when creating directories (bsc#1139959).

Non-security issue fixed: Added explicit requires between libglib2 and libgio2 (bsc#1140122).

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

An update of the glib package has been released.

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 Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1586 advisory.

    GNOME is the default desktop environment of Red Hat Enterprise Linux.

    The following packages have been upgraded to a later upstream version: accountsservice (0.6.55),     webkit2gtk3 (2.30.4). (BZ#1846376, BZ#1883304)

    Security Fix(es):

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

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

    * webkitgtk: out-of-bounds write may lead to code execution (CVE-2020-9983)

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

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

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

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

  - A memory corruption issue was addressed with improved state management. This issue is fixed in macOS Big     Sur 11.3, iOS 14.5 and iPadOS 14.5, watchOS 7.4, tvOS 14.5. Processing maliciously crafted web content may     lead to arbitrary code execution. (CVE-2021-1817)

  - A memory initialization issue was addressed with improved memory handling. This issue is fixed in macOS     Big Sur 11.3, iOS 14.5 and iPadOS 14.5, watchOS 7.4, tvOS 14.5. Processing maliciously crafted web content     may result in the disclosure of process memory. (CVE-2021-1820)

  - An input validation issue was addressed with improved input validation. This issue is fixed in iTunes     12.11.3 for Windows, iCloud for Windows 12.3, macOS Big Sur 11.3, Safari 14.1, watchOS 7.4, tvOS 14.5, iOS     14.5 and iPadOS 14.5. Processing maliciously crafted web content may lead to a cross site scripting     attack. (CVE-2021-1825)

  - A logic issue was addressed with improved restrictions. This issue is fixed in macOS Big Sur 11.3, iOS     14.5 and iPadOS 14.5, watchOS 7.4, tvOS 14.5. Processing maliciously crafted web content may lead to     universal cross site scripting. (CVE-2021-1826)

  - A use after free issue was addressed with improved memory management. This issue is fixed in Safari 14.1,     iOS 12.5.3, iOS 14.5 and iPadOS 14.5, watchOS 7.4, tvOS 14.5, macOS Big Sur 11.3. Processing maliciously     crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may     have been actively exploited.. (CVE-2021-30661)

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)
