Echo: openssl-1.1.1c: security update to 1.1.1c+e1

medium Tenable Self-Hosted Container Security Plugin ID 478579

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit
 moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime
 RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed
 likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have
 to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low
 level API BN_mod_exp may be affected if they use BN_FLG_CONSTTIME. Fixed in OpenSSL 1.1.1e (Affected
 1.1.1-1.1.1d). Fixed in OpenSSL 1.0.2u (Affected 1.0.2-1.0.2t). (CVE-2019-1551)

Solution

Update the openssl-1.1.1c library and its related packages to version 1.1.1c+e1 or later.
