EUVDB-ID: #VU23845

Risk: Low

CVSSv4.0: 0.4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-15945

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when processing ASN.1 Bitstring within the decode_bit_string() function in libopensc/asn1.c. A local user can pass specially crafted data to the application, trigger out-of-bounds read error and read contents of memory on the system.

Mitigation

Update the affected package opensc to the latest version.

EUVDB-ID: #VU66141

Risk: Low

CVSSv4.0: 0.1 [CVSS:4.0/AV:P/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-42781

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows an attacker with physical access to perform denial of service attack.

The vulnerability exists due to a boundary error in Opensc before in pkcs15-oberthur.c. An attacker with physical access can pass specially crafted data to the application, trigger a heap-based buffer overflow and perform denial of service attack.

Mitigation

Update the affected package opensc to the latest version.
