SB20250228115 - openEuler 24.03 LTS update for edk2

Description

This security bulletin contains information about 3 vulnerabilities.

1) Cryptographic issues (CVE-ID: CVE-2023-5363)

CWE-ID: CWE-310 - Cryptographic Issues

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to an error when processing key and initialisation vector lengths in EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() and EVP_CipherInit_ex2() function. A remote attacker can gain access to potentially sensitive information.

The following ciphers and cipher modes are impacted: RC2, RC4, RC5, CCM, GCM and OCB.

2) Covert Timing Channel (CVE-ID: CVE-2024-13176)

CWE-ID: CWE-385 - Covert Timing Channel

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to recover a private key.

The vulnerability exists due to a timing side-channel in ECDSA signature computations. A remote attacker can recover the private key and decrypt data.

Successful exploitation of the vulnerability requires that the attacker's process must either be located in the same physical computer or must have a very fast network connection with low latency.

3) Use-after-free (CVE-ID: CVE-2024-4741)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the SSL_free_buffers() function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.

Note, the vulnerability affects only applications that call the vulnerable function.

Remediation
