Alpine: openssl: security update to 1.0.2k-r0
medium Tenable Self-Hosted Container Security Plugin ID 406082
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL
1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis
suggests that attacks against RSA, DSA and DH private keys are impossible. This is because the subroutine
in question is not used in operations with the private key itself and an input of the attacker's direct
choice. Otherwise the bug can manifest itself as transient authentication and key negotiation failures or
reproducible erroneous outcome of public-key operations with specially crafted input. Among EC algorithms
only Brainpool P-512 curves are affected and one presumably can attack ECDH key negotiation. Impact was
not analyzed in detail, because pre-requisites for attack are considered unlikely. Namely multiple clients
have to choose the curve in question and the server has to share the private key among them, neither of
which is default behaviour. Even then only clients that chose the curve will be affected. (CVE-2016-7055)
- If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a
truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a
crash. For OpenSSL 1.1.0, the crash can be triggered when using CHACHA20/POLY1305; users should upgrade to
1.1.0d. For Openssl 1.0.2, the crash can be triggered when using RC4-MD5; users who have not disabled that
algorithm should update to 1.0.2k. (CVE-2017-3731)
- There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL 1.0.2 before
1.0.2k and 1.1.0 before 1.1.0d. No EC algorithms are affected. Analysis suggests that attacks against RSA
and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks
against DH are considered just feasible (although very difficult) because most of the work necessary to
deduce information about a private key may be performed offline. The amount of resources required for such
an attack would be very significant and likely only accessible to a limited number of attackers. An
attacker would additionally need online access to an unpatched system using the target private key in a
scenario with persistent DH parameters and a private key that is shared between multiple clients. For
example this can occur by default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very
similar to CVE-2015-3193 but must be treated as a separate problem. (CVE-2017-3732)
