CVE-2021-28153 4 Broadcom, Debian, Fedoraproject and 1 more 4 Brocade Fabric Operating System Firmware, Debian Linux, Fedora and 1 more 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
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-2021-27219 5 Broadcom, Debian, Fedoraproject and 2 more 7 Brocade Fabric Operating System Firmware, Debian Linux, Fedora and 4 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
An issue was discovered in GNOME GLib before 2.66.6 and 2.67.x before 2.67.3. The function g_bytes_new has an integer overflow on 64-bit platforms due to an implicit cast from 64 bits to 32 bits. The overflow could potentially lead to memory corruption.
CVE-2021-27218 5 Broadcom, Debian, Fedoraproject and 2 more 7 Brocade Fabric Operating System Firmware, Debian Linux, Fedora and 4 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
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-2020-6750 2 Fedoraproject, Gnome 2 Fedora, Glib 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
GSocketClient in GNOME GLib through 2.62.4 may occasionally connect directly to a target address instead of connecting via a proxy server when configured to do so, because the proxy_addr field is mishandled. This bug is timing-dependent and may occur only sporadically depending on network delays. The greatest security relevance is in use cases where a proxy is used to help with privacy/anonymity, even though there is no technical barrier to a direct connection. NOTE: versions before 2.60 are unaffected.
CVE-2020-35457 1 Gnome 1 Glib 2026-06-17 4.6 MEDIUM 7.8 HIGH
GNOME GLib before 2.65.3 has an integer overflow, that might lead to an out-of-bounds write, in g_option_group_add_entries. NOTE: the vendor's position is "Realistically this is not a security issue. The standard pattern is for callers to provide a static list of option entries in a fixed number of calls to g_option_group_add_entries()." The researcher states that this pattern is undocumented
CVE-2019-9633 1 Gnome 1 Glib 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
gio/gsocketclient.c in GNOME GLib 2.59.2 does not ensure that a parent GTask remains alive during the execution of a connection-attempting enumeration, which allows remote attackers to cause a denial of service (g_socket_client_connected_callback mishandling and application crash) via a crafted web site, as demonstrated by GNOME Web (aka Epiphany).
CVE-2019-13012 1 Gnome 1 Glib 2026-06-17 5.0 MEDIUM 7.5 HIGH
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-2019-12450 6 Canonical, Debian, Fedoraproject and 3 more 9 Ubuntu Linux, Debian Linux, Fedora and 6 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
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-2018-16429 2 Canonical, Gnome 2 Ubuntu Linux, Glib 2026-06-17 5.0 MEDIUM 7.5 HIGH
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-2018-16428 2 Canonical, Gnome 2 Ubuntu Linux, Glib 2026-06-17 7.5 HIGH 9.8 CRITICAL
In GNOME GLib 2.56.1, g_markup_parse_context_end_parse() in gmarkup.c has a NULL pointer dereference.
CVE-2016-6855 4 Canonical, Fedoraproject, Gnome and 1 more 6 Ubuntu Linux, Fedora, Eye Of Gnome and 3 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
Eye of GNOME (aka eog) 3.16.5, 3.17.x, 3.18.x before 3.18.3, 3.19.x, and 3.20.x before 3.20.4, when used with glib before 2.44.1, allow remote attackers to cause a denial of service (out-of-bounds write and crash) via vectors involving passing invalid UTF-8 to GMarkup.
CVE-2013-1978 3 Gimp, Gnome, Redhat 3 Gimp, Glib, Enterprise Linux 2026-06-16 6.8 MEDIUM N/A
Heap-based buffer overflow in the read_xwd_cols function in file-xwd.c in the X Window Dump (XWD) plug-in in GIMP 2.6.9 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an X Window System (XWD) image dump with more colors than color map entries.
CVE-2013-1913 3 Gimp, Gnome, Redhat 3 Gimp, Glib, Enterprise Linux 2026-06-16 6.8 MEDIUM N/A
Integer overflow in the load_image function in file-xwd.c in the X Window Dump (XWD) plug-in in GIMP 2.6.9 and earlier, when used with glib before 2.24, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large color entries value in an X Window System (XWD) image dump.
CVE-2012-0039 1 Gnome 1 Glib 2026-06-16 5.0 MEDIUM 7.5 HIGH
GLib 2.31.8 and earlier, when the g_str_hash function is used, computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this issue may be disputed by the vendor; the existence of the g_str_hash function is not a vulnerability in the library, because callers of g_hash_table_new and g_hash_table_new_full can specify an arbitrary hash function that is appropriate for the application.
CVE-2011-1709 1 Gnome 2 Gdm, Glib 2026-06-16 7.2 HIGH N/A
GNOME Display Manager (gdm) before 2.32.2, when glib 2.28 is used, enables execution of a web browser with the uid of the gdm account, which allows local users to gain privileges via vectors involving the x-scheme-handler/http MIME type.
CVE-2009-3289 3 Gnome, Opensuse, Suse 3 Glib, Opensuse, Suse Linux Enterprise Server 2026-06-16 4.4 MEDIUM 7.8 HIGH
The g_file_copy function in glib 2.0 sets the permissions of a target file to the permissions of a symbolic link (777), which allows user-assisted local users to modify files of other users, as demonstrated by using Nautilus to modify the permissions of the user home directory.
CVE-2008-4316 1 Gnome 1 Glib 2026-06-16 4.6 MEDIUM N/A
Multiple integer overflows in glib/gbase64.c in GLib before 2.20 allow context-dependent attackers to execute arbitrary code via a long string that is converted either (1) from or (2) to a base64 representation.
