Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Memory leak

EUVDB-ID: #VU87830

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-1394

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in the RSA encrypting/decrypting code when handling untrusted input. A remote attacker can pass specially crafted data to the application and perform denial of service attack.

Mitigation

Install updates from vendor's repository.

2) Resource exhaustion

EUVDB-ID: #VU97217

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-34158

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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

The vulnerability exists due to go/build/constraint does not properly control consumption of internal resources when calling Parse on a "// +build" build tag line with deeply nested expressions. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

3) Use of Uninitialized Variable

EUVDB-ID: #VU98022

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-9355

CWE-ID: CWE-457 - Use of Uninitialized Variable

Exploit availability: No

Description

The vulnerability allows a remote attacker to weaken TLS encryption.

The vulnerability exists due to an uninitialized buffer length variable in the CGO bindings that intermittently return a zeroed buffer from (*boringHMAC).Sum() in FIPS mode. A remote attacker can randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode and weaken TLS security.

Mitigation

Install updates from vendor's repository.
