Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-4948 advisory.

- libaspell.a in GNU Aspell before 0.60.8 has a stack-based buffer over-read in acommon::unescape in common/getdata.cpp via an isolated \ character. (CVE-2019-17544)

- objstack in GNU Aspell 0.60.8 has a heap-based buffer overflow in acommon::ObjStack::dup_top (called from acommon::StringMap::add and acommon::Config::lookup_list). (CVE-2019-25051)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the aspell packages.

For the stable distribution (buster), these problems have been fixed in version 0.60.7~20110707-6+deb10u1.
