Vulnerabilidades

An exploitable heap-based buffer overflow vulnerability exists in the read_legacy_biff function of FreeXL 1.0.3. A specially crafted XLS file can cause a memory corruption resulting in remote code execution. An attacker can send malicious XLS file to trigger this vulnerability.

An exploitable heap based buffer overflow vulnerability exists in the 'read_biff_next_record function' of FreeXL 1.0.3. A specially crafted XLS file can cause a memory corruption resulting in remote code execution. An attacker can send malicious XLS file to trigger this vulnerability.

An issue was discovered in FreeXL before 1.0.5. There is a heap-based buffer over-read in the function read_mini_biff_next_record.

An issue was discovered in FreeXL before 1.0.5. There is a heap-based buffer over-read in the parse_unicode_string function.

An issue was discovered in FreeXL before 1.0.5. There is a heap-based buffer over-read in a memcpy call of the parse_SST function.

An issue was discovered in FreeXL before 1.0.5. There is a heap-based buffer over-read in a pointer dereference of the parse_SST function.

An issue was discovered in FreeXL before 1.0.5. There is a heap-based buffer over-read in the freexl::destroy_cell function.

The parse_SST function in FreeXL before 1.0.0i allows remote attackers to cause a denial of service (memory consumption) via a crafted shared strings table in a workbook.

FreeXL before 1.0.0i allows remote attackers to cause a denial of service (stack corruption) and possibly execute arbitrary code via a crafted workbook, related to a "premature EOF."

FreeXL before 1.0.0i allows remote attackers to cause a denial of service (stack corruption) or possibly execute arbitrary code via a crafted sector in a workbook.
