CWE-385
Covert Timing Channel
Covert timing channels convey information by modulating some aspect of system behavior over time, so that the program receiving the information can observe system behavior and infer protected information.
CVE-2025-9231 (GCVE-0-2025-9231)

Title
Timing side-channel in SM2 algorithm on 64 bit ARM
Summary
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.

Title
PostgreSQL discloses MD5-hashed passwords via covert timing channel
Summary
Covert timing channel in comparison of MD5-hashed password in PostgreSQL authentication allows an attacker to recover user credentials sufficient to authenticate. This does not affect scram-sha-256 passwords, the default in all supported releases. However, current databases may have MD5-hashed passwords originating in upgrades from PostgreSQL 13 or earlier. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

For example, to change a user\u0027s password: `ALTER USER username WITH PASSWORD \u0027new_password\u0027;` This action will require users to re-authenticate. If a service relies on these credentials, it may require a restart to pick up the new authentication details."

Mitigation
Phase: Architecture and Design
Description:
- Whenever possible, specify implementation strategies that do not introduce time variances in operations.
Mitigation
Phase: Implementation
Description:
- Often one can artificially manipulate the time which operations take or -- when operations occur -- can remove information from the attacker.
Mitigation
Phase: Implementation
Description:
- It is reasonable to add artificial or random delays so that the amount of CPU time consumed is independent of the action being taken by the application.
CAPEC-462: Cross-Domain Search Timing
An attacker initiates cross domain HTTP / GET requests and times the server responses. The timing of these responses may leak important information on what is happening on the server. Browser's same origin policy prevents the attacker from directly reading the server responses (in the absence of any other weaknesses), but does not prevent the attacker from timing the responses to requests that the attacker issued cross domain.
