Synopsis

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

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2810 advisory.

It was discovered that there were a number of issues in redis, a popular key-value database system:
CVE-2021-41099: Integer to heap buffer overflow handling certain string commands and network payloads, when proto-max-bulk-len is manually configured to a non-default, very large value. CVE-2021-32762: Integer to heap buffer overflow issue in redis-cli and redis-sentinel parsing large multi-bulk replies on some older and less common platforms. CVE-2021-32687: Integer to heap buffer overflow with intsets, when set- max-intset-entries is manually configured to a non-default, very large value. CVE-2021-32675: Denial Of Service when processing RESP request payloads with a large number of elements on many connections.
CVE-2021-32672: Random heap reading issue with Lua Debugger. CVE-2021-32626: Specially crafted Lua scripts may result with Heap buffer overflow. For Debian 9 Stretch, these problems have been fixed in version 3:3.2.6-3+deb9u8. We recommend that you upgrade your redis packages.
