0 An out-of-bounds read vulnerability exists in the xls_dumpSummary() function of libxls 1.6.3 due to insufficient validation of file-controlled OLE summary offsets. Join the discussion | CVE Database V5 | 09/10/2026, 00:00:00 UTC Added: 09/10/2026, 20:47:29 UTC |
0 A heap-buffer-overflow and use-after-free vulnerability exists in the xls_getCSS() function of libxls 1.6.3 due to insufficient validation of a file-controlled font index. Join the discussion | CVE Database V5 | 09/10/2026, 00:00:00 UTC Added: 09/10/2026, 20:47:29 UTC |
0 A use-of-uninitialized memory vulnerability exists in libxls 1.6.3 when parsing malformed XLS files. The issue is reachable via xls_parseWorkBook() and is triggered by uninitialized heap memory originating from the OLE layer (ole2_read). The flaw is detectable with MemorySanitizer (MSAN) and can lead to undefined behavior, incorrect parsing logic, or potential information disclosure.

0 libxls through version 1.6.3 contains a use of uninitialized memory vulnerability in the OLE container parser. Memory allocated for the Master Sector Allocation Table (MSAT) in read_MSAT() is not fully initialized before being consumed by ole2_validate_sector_chain(), which may result in application crashes or potential information disclosure when processing a crafted XLS file Join the discussion | CVE Database V5 | 06/03/2026, 00:00:00 UTC Added: 06/03/2026, 20:18:39 UTC |
0 Buffer Overflow vulnerability in libxlsv.1.6.2 allows a remote attacker to execute arbitrary code and cause a denial of service via a crafted XLS file to the unicode_decode_wcstombs function in xlstool.c:266.
