TencentOS Server 3: opensc (TSSA-2022:0089)

medium Nessus Plugin ID 239948

Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2022:0089 advisory.

 Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

 CVE-2020-26570:
 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-2020-26571:
 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-2020-26572:
 The TCOS smart card software driver in OpenSC before 0.21.0-rc1 has a stack-based buffer overflow in tcos_decipher.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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