catdoc through 0.95 contains an out-of-bounds read vulnerability in copy_unicode_string() in src/xlsparse.c that allows attackers to read past buffers via an unchecked string character count. Attackers can supply a crafted .xls file declaring 0xFFFF two-byte characters in LABEL, STRING, or SST records to disclose adjacent memory through xls2csv output or crash the process.
catdoc through 0.95 contains an out-of-bounds read vulnerability in the MULRK record handler of process_item() in src/xlsparse.c that allows attackers to read past the static rec buffer via a crafted end column. Attackers can supply a crafted .xls workbook or BIFF stream with a large endcol to xls2csv to disclose adjacent process memory as CSV cells or crash the process.
Catdoc v0.95 was discovered to contain a NULL pointer dereference via the component xls2csv at src/xlsparse.c.
Catdoc v0.95 was discovered to contain a NULL pointer dereference via the component xls2csv at src/fileutil.c.
Catdoc v0.95 was discovered to contain a global buffer overflow via the function process_file at /src/reader.c.
In libdoc through 2019-01-28, doc2text in catdoc.c has a NULL pointer dereference.
In libdoc through 2019-01-28, calcFileBlockOffset in ole.c allows division by zero.
The getlong function in numutils.c in libdoc through 2017-10-23 has a heap-based buffer over-read that allows attackers to cause a denial of service (application crash) via a crafted file.
The process_file function in reader.c in libdoc through 2017-10-23 has a heap-based buffer over-read that allows attackers to cause a denial of service (application crash) via a crafted file.
