CWE-125

In LibTomCrypt through 1.18.2, the der_decode_utf8_string function (in der_decode_utf8_string.c) does not properly detect certain invalid UTF-8 sequences. This allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) or read information from other memory locations via carefully crafted DER-encoded data.

MPC-HC through 1.7.13 allows a Read Access Violation on a Block Data Move starting at mpc_hc!memcpy+0x000000000000004e.

** DISPUTED ** In libyal libfwsi before 20191006, libfwsi_extension_block_copy_from_byte_stream in libfwsi_extension_block.c has a heap-based buffer over-read because rejection of an unsupported size only considers values less than 6, even though values of 6 and 7 are also unsupported. NOTE: the vendor has disputed this as described in the GitHub issue.

** DISPUTED ** In libyal liblnk before 20191006, liblnk_location_information_read_data in liblnk_location_information.c has a heap-based buffer over-read because an incorrect variable name is used for a certain offset. NOTE: the vendor has disputed this as described in the GitHub issue.

libsoup from versions 2.65.1 until 2.68.1 have a heap-based buffer over-read because soup_ntlm_parse_challenge() in soup-auth-ntlm.c does not properly check an NTLM message’s length before proceeding with a memcpy.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PhantomPDF 9.5.0.20723. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the conversion of DXF files to PDF. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-8776.
