- ------------------------------------------------------------------------- Debian LTS Advisory DLA-3530-1 [email protected] https://www.debian.org/lts/security/ Anton Gladky August 15, 2023 https://wiki.debian.org/LTS
- -------------------------------------------------------------------------

Package : openssl Version : 1.1.1n-0+deb10u6 CVE ID : CVE-2023-3446 CVE-2023-3817

Two vunerabilities were discovered in openssl, a Secure Sockets Layer toolkit:

CVE-2023-3446, CVE-2023-3817

Excessively long DH key or parameter checks can cause significant delays in applications using DH_check(), DH_check_ex(), or EVP_PKEY_param_check() functions, potentially leading to Denial of Service attacks when keys or parameters are obtained from untrusted sources.


For Debian 10 buster, these problems have been fixed in version 1.1.1n-0+deb10u6.

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

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 libssl-dev packages.
