Debian DSA-5103-1 : openssl - security update

medium Nessus Plugin ID 158979

Language:

Synopsis

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

Description

The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5103 advisory.

 Tavis Ormandy discovered that the BN_mod_sqrt() function of OpenSSL could be tricked into an infinite loop. This could result in denial of service via malformed certificates. Additional details can be found in the upstream advisory: https://www.openssl.org/news/secadv/20220315.txt In addition this update corrects a carry propagation bug specific to MIPS architectures. For the oldstable distribution (buster), this problem has been fixed in version 1.1.1d-0+deb10u8. For the stable distribution (bullseye), this problem has been fixed in version 1.1.1k-1+deb11u2. We recommend that you upgrade your openssl packages.
 For the detailed security status of openssl please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/openssl

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

Solution

Upgrade the openssl packages.

For the stable distribution (bullseye), this problem has been fixed in version 1.1.1k-1+deb11u2.
