catdoc through 0.95 Out-of-Bounds Read via xls2csv copy_unicode_string
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 Out-of-Bounds Read in xls2csv MULRK Record Handler
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.
A memory corruption vulnerability exists in the Shared String Table Record Parser implementation in xls2csv utility version 0.95. A specially crafted malformed file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.
An integer overflow vulnerability exists in the OLE Document File Allocation Table Parser functionality of catdoc 0.95. A specially crafted malformed file can lead to heap-based memory corruption. An attacker can provide a malicious file to trigger this vulnerability.
An integer underflow vulnerability exists in the OLE Document DIFAT Parser functionality of catdoc 0.95. A specially crafted malformed file can lead to heap-based memory corruption. An attacker can provide a malicious file to trigger this vulnerability.
