Alpine: libcrypto3, multiple openssl packages: security update to 3.1.4-r3
medium Tenable Cloud Security Plugin ID 424302
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Issue summary: The POLY1305 MAC (message authentication code) implementation contains a bug that might
corrupt the internal state of applications running on PowerPC CPU based platforms if the CPU provides
vector instructions. Impact summary: If an attacker can influence whether the POLY1305 MAC algorithm is
used, the application state might be corrupted with various application dependent consequences. The
POLY1305 MAC (message authentication code) implementation in OpenSSL for PowerPC CPUs restores the
contents of vector registers in a different order than they are saved. Thus the contents of some of these
vector registers are corrupted when returning to the caller. The vulnerable code is used only on newer
PowerPC processors supporting the PowerISA 2.07 instructions. The consequences of this kind of internal
application state corruption can be various - from no consequences, if the calling application does not
depend on the contents of non-volatile XMM registers at all, to the worst consequences, where the attacker
could get complete control of the application process. However unless the compiler uses the vector
registers for storing pointers, the most likely consequence, if any, would be an incorrect result of some
application dependent calculations or a crash leading to a denial of service. The POLY1305 MAC algorithm
is most frequently used as part of the CHACHA20-POLY1305 AEAD (authenticated encryption with associated
data) algorithm. The most common usage of this AEAD cipher is with TLS protocol versions 1.2 and 1.3. If
this cipher is enabled on the server a malicious client can influence whether this AEAD cipher is used.
This implies that TLS server applications using OpenSSL can be potentially impacted. However we are
currently not aware of any concrete application that would be affected by this issue therefore we consider
this a Low severity security issue. (CVE-2023-6129)
