Alpine: libcrypto3, multiple openssl packages: security update to 3.5.4-r0
medium Tenable Cloud Security Plugin ID 435467
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- Issue summary: An application trying to decrypt CMS messages encrypted using password based encryption can
trigger an out-of-bounds read and write. Impact summary: This out-of-bounds read may trigger a crash which
leads to Denial of Service for an application. The out-of-bounds write can cause a memory corruption which
can have various consequences including a Denial of Service or Execution of attacker-supplied code.
Although the consequences of a successful exploit of this vulnerability could be severe, the probability
that the attacker would be able to perform it is low. Besides, password based (PWRI) encryption support in
CMS messages is very rarely used. For that reason the issue was assessed as Moderate severity according to
our Security Policy. The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue,
as the CMS implementation is outside the OpenSSL FIPS module boundary. (CVE-2025-9230)
- Issue summary: A timing side-channel which could potentially allow remote recovery of the private key
exists in the SM2 algorithm implementation on 64 bit ARM platforms. Impact summary: A timing side-channel
in SM2 signature computations on 64 bit ARM platforms could allow recovering the private key by an
attacker.. While remote key recovery over a network was not attempted by the reporter, timing measurements
revealed a timing signal which may allow such an attack. OpenSSL does not directly support certificates
with SM2 keys in TLS, and so this CVE is not relevant in most TLS contexts. However, given that it is
possible to add support for such certificates via a custom provider, coupled with the fact that in such a
custom provider context the private key may be recoverable via remote timing measurements, we consider
this to be a Moderate severity issue. The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected
by this issue, as SM2 is not an approved algorithm. (CVE-2025-9231)
- Issue summary: An application using the OpenSSL HTTP client API functions may trigger an out-of-bounds
read if the 'no_proxy' environment variable is set and the host portion of the authority component of the
HTTP URL is an IPv6 address. Impact summary: An out-of-bounds read can trigger a crash which leads to
Denial of Service for an application. The OpenSSL HTTP client API functions can be used directly by
applications but they are also used by the OCSP client functions and CMP (Certificate Management Protocol)
client implementation in OpenSSL. However the URLs used by these implementations are unlikely to be
controlled by an attacker. In this vulnerable code the out of bounds read can only trigger a crash.
Furthermore the vulnerability requires an attacker-controlled URL to be passed from an application to the
OpenSSL function and the user has to have a 'no_proxy' environment variable set. For the aforementioned
reasons the issue was assessed as Low severity. The vulnerable code was introduced in the following patch
releases: 3.0.16, 3.1.8, 3.2.4, 3.3.3, 3.4.0 and 3.5.0. The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and
3.0 are not affected by this issue, as the HTTP client implementation is outside the OpenSSL FIPS module
boundary. (CVE-2025-9232)
