Debian DLA-1297-1 : freexl security update

Synopsis

The remote Debian host is missing a security update.

Description

Leon reported five heap-based buffer-overflow vulnerabilities in FreeXL.

CVE-2018-7435

There is a heap-based buffer over-read in the freexl::destroy_cell function.

CVE-2018-7436

There is a heap-based buffer over-read in a pointer dereference of the parse_SST function.

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.

Solution
