[SECURITY] Fedora 42 Update: mbedtls-3.6.4-1.fc42

Mbed TLS is a light-weight open source cryptographic and SSL/TLS library written in C. Mbed TLS makes it easy for developers to include cryptographic and SSL/TLS capabilities in their embedded applications with as little hassle as possible...

CVE-2025-52497

A flaw was found in mbedtls. The mbedtlspemreadbuffer and two mbedtlspkparse functions exhibit a one-byte heap-based buffer underflow when parsing untrusted PEM input. This flaw allows a network-based attacker to trigger the underflow by providing a maliciously crafted PEM file, resulting in a...

CVE-2025-52496

A flaw was found in mbedtls. A race condition exists during Advanced Encryption Standard New Instructions AES-NI detection when specific compiler optimizations are enabled. This flaw allows a local attacker to potentially extract an AES key or perform a GCM forgery within a multithreaded program...

SUSE CVE-2025-52496

Mbed TLS before 3.6.4 has a race condition in AESNI detection if certain compiler optimizations occur. An attacker may be able to extract an AES key from a multithreaded program, or perform a GCM forgery...

SUSE CVE-2025-52497

Mbed TLS before 3.6.4 has a PEM parsing one-byte heap-based buffer underflow, in mbedtlspemreadbuffer and two mbedtlspkparse functions, via untrusted PEM input...

Compiler Optimization Removal or Modification of Security-critical Code

Overview Affected versions of this package are vulnerable to Compiler Optimization Removal or Modification of Security-critical Code due to a race condition in AESNI detection when certain compiler optimizations are applied. An attacker can extract sensitive cryptographic keys or perform...

ALPINE-CVE-2025-49601

In MbedTLS 3.3.0 before 3.6.4, mbedtlslmsimportpublickey does not check that the input buffer is at least 4 bytes before reading a 32-bit field, allowing a possible out-of-bounds read on truncated input. Specifically, an out-of-bounds read in mbedtlslmsimportpublickey allows context-dependent...

UBUNTU-CVE-2025-49600

In MbedTLS 3.3.0 before 3.6.4, mbedtlslmsverify may accept invalid signatures if hash computation fails and internal errors go unchecked, enabling LMS Leighton-Micali Signature forgery in a fault scenario. Specifically, unchecked return values in mbedtlslmsverify allow an attacker who can induce ...
