CVE-2026-103678 [HIGH] CWE-125 CVE-2026-103678: A flaw was found in tnef. An attacker can exploit this vulnerability by providing a specially crafte A flaw was found in tnef. An attacker can exploit this vulnerability by providing a specially crafted file containing uncompressed Rich Text Format (RTF) data. Because the application fails to properly validate input buffer boundaries before copying data in get_rtf_data_from_buf(), reading beyond the allocated memory occurs. This flaw can cause the

CVE-2017-8911 [CRITICAL] CWE-191 CVE-2017-8911: An integer underflow has been identified in the unicode_to_utf8() function in tnef 1.4.14. This migh An integer underflow has been identified in the unicode_to_utf8() function in tnef 1.4.14. This might lead to invalid write operations, controlled by an attacker.

CVE-2017-6310 [HIGH] CWE-125 CVE-2017-6310: An issue was discovered in tnef before 1.4.13. Four type confusions have been identified in the file An issue was discovered in tnef before 1.4.13. Four type confusions have been identified in the file_add_mapi_attrs() function. These might lead to invalid read and write operations, controlled by an attacker.

CVE-2017-6307 [HIGH] CWE-787 CVE-2017-6307: An issue was discovered in tnef before 1.4.13. Two OOB Writes have been identified in src/mapi_attr. An issue was discovered in tnef before 1.4.13. Two OOB Writes have been identified in src/mapi_attr.c:mapi_attr_read(). These might lead to invalid read and write operations, controlled by an attacker.

CVE-2017-6309 [HIGH] CWE-125 CVE-2017-6309: An issue was discovered in tnef before 1.4.13. Two type confusions have been identified in the parse An issue was discovered in tnef before 1.4.13. Two type confusions have been identified in the parse_file() function. These might lead to invalid read and write operations, controlled by an attacker.

CVE-2017-6308 [HIGH] CWE-190 CVE-2017-6308: An issue was discovered in tnef before 1.4.13. Several Integer Overflows, which can lead to Heap Ove An issue was discovered in tnef before 1.4.13. Several Integer Overflows, which can lead to Heap Overflows, have been identified in the functions that wrap memory allocation.

CVE-2026-103680 [MEDIUM] CWE-787 CVE-2026-103680: A flaw was found in tnef. A heap-based buffer overflow can occur in the find_free_number() function A flaw was found in tnef. A heap-based buffer overflow can occur in the find_free_number() function when generating numbered backup suffixes for duplicate filenames. When numbered backups are enabled and file overwriting is disabled, an attacker can supply a specially crafted Transport Neutral Encapsulation Format (TNEF) file with an excessive numb

CVE-2026-103679 [MEDIUM] CWE-416 CVE-2026-103679: A flaw was found in tnef. A remote attacker could exploit this vulnerability by providing a speciall A flaw was found in tnef. A remote attacker could exploit this vulnerability by providing a specially crafted Transport Neutral Encapsulation Format (TNEF) file containing multiple message bodies. During extraction, improper memory management triggers a use-after-free and double-free condition, causing the application to crash and resulting in a D

CVE-2019-18849 [MEDIUM] CWE-125 CVE-2019-18849: In tnef before 1.4.18, an attacker may be able to write to the victim's .ssh/authorized_keys file vi In tnef before 1.4.18, an attacker may be able to write to the victim's .ssh/authorized_keys file via an e-mail message with a crafted winmail.dat application/ms-tnef attachment, because of a heap-based buffer over-read involving strdup.
