Vulnerabilidades

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.

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.

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.

The ole_init function in ole.c in catdoc 0.95 allows remote attackers to cause a denial of service (heap-based buffer underflow and application crash) or possibly have unspecified other impact via a crafted file, i.e., data is written to memory addresses before the beginning of the tmpBuf buffer.

msxlsview.sh in xlsview for catdoc 0.91 and earlier allows local users to overwrite arbitrary files via a symlink attack on predictable temporary file names ("word$$.html").
