| CVE-2009-3289 | Hig | 0.51 | 7.8 | 0.00 | | Sep 22, 2009 | 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-2012-0039 | Hig | 0.49 | 7.5 | 0.00 | | Jan 14, 2012 | 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-2025-13601 | Hig | 0.43 | 7.7 | 0.00 | | Nov 26, 2025 | A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string. |
| CVE-2025-14512 | Med | 0.35 | 6.5 | 0.00 | | Dec 11, 2025 | A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing malicious file or remote filesystem attribute values. |
| CVE-2025-14087 | Med | 0.29 | 5.6 | 0.00 | | Dec 10, 2025 | A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings. |
| CVE-2026-0988 | Low | 0.24 | 3.7 | 0.00 | | Jan 21, 2026 | A flaw was found in glib. Missing validation of offset and count parameters in the g_buffered_input_stream_peek() function can lead to an integer overflow during length calculation. When specially crafted values are provided, this overflow results in an incorrect size being passed to memcpy(), triggering a buffer overflow. This can cause application crashes, leading to a Denial of Service (DoS). |
| CVE-2008-4316 | | 0.00 | — | 0.00 | | Mar 14, 2009 | 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. |
