The key_certify function in usr.bin/ssh/key.c in OpenSSH 5.6 and 5.7, when generating legacy certificates using the -t command-line option in ssh-keygen, does not initialize the nonce field, which might allow remote attackers to obtain sensitive stack memory contents or make it easier to conduct hash collision attacks.

Vulnerability from github – Published: 2024-10-01 21:31 – Updated: 2026-08-25 15:31
VLAI
Summary
Golang FIPS OpenSSL has a Use of Uninitialized Variable vulnerability
Details

A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted computed hmac sum to an untrusted input sum if an attacker can send a zeroed buffer in place of a pre-computed sum.  It is also possible to force a derived key to be all zeros instead of an unpredictable value.  This may have follow-on implications for the Go TLS stack.

This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted computed hmac sum to an untrusted input sum if an attacker can send a zeroed buffer in place of a pre-computed sum.\u00a0 It is also possible to force a derived key to be all zeros instead of an unpredictable value.\u00a0 This may have follow-on implications for the Go TLS stack.",

Mitigation MIT-57
Implementation

Strategy: Attack Surface Reduction

Ensure that critical variables are initialized before first use [REF-1485].

Mitigation
Build and Compilation

Strategy: Compilation or Build Hardening

Most compilers will complain about the use of uninitialized variables if warnings are turned on.

Mitigation
Implementation Operation

When using a language that does not require explicit declaration of variables, run or compile the software in a mode that reports undeclared or unknown variables. This may indicate the presence of a typographic error in the variable's name.

Mitigation
Requirements

Strategy: Language Selection

Choose a language that is not susceptible to these issues.

Mitigation
Architecture and Design

Mitigating technologies such as safe string libraries and container abstractions could be introduced.

No CAPEC attack patterns related to this CWE.
