"The Cisco Talos team reported two sensitive security issues affecting
FreeXL-1.0.3 and any previous version.

CVE-2017-2923

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.

CVE-2017-2924

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.

For Debian 7 'Wheezy', these problems have been fixed in version
1.0.0b-1+deb7u4.

We recommend that you upgrade your freexl packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
