Amazon Linux 2 : opensc (ALAS-2023-2262)

medium Nessus Plugin ID 181721

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of opensc installed on the remote host is prior to 0.19.0-5. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2262 advisory.

OpenSC before 0.20.0-rc1 has an out-of-bounds access of an ASN.1 Bitstring in decode_bit_string in libopensc/asn1.c. (CVE-2019-15945)

OpenSC before 0.20.0-rc1 has an out-of-bounds access of an ASN.1 Octet string in asn1_decode_entry in libopensc/asn1.c. (CVE-2019-15946)

An issue was discovered in OpenSC through 0.19.0 and 0.20.x through 0.20.0-rc3. libopensc/card-setcos.c has an incorrect read operation during parsing of a SETCOS file attribute. (CVE-2019-19479)

OpenSC before 0.20.0 has a double free in coolkey_free_private_data because coolkey_add_object in libopensc/card-coolkey.c lacks a uniqueness check. (CVE-2019-20792)

The Oberthur smart card software driver in OpenSC before 0.21.0-rc1 has a heap-based buffer overflow in sc_oberthur_read_file. (CVE-2020-26570)

The gemsafe GPK smart card software driver in OpenSC before 0.21.0-rc1 has a stack-based buffer overflow in sc_pkcs15emu_gemsafeGPK_init. (CVE-2020-26571)

The TCOS smart card software driver in OpenSC before 0.21.0-rc1 has a stack-based buffer overflow in tcos_decipher. (CVE-2020-26572)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update opensc' to update your system.
