Name of the Vulnerable Software and Affected Versions OpenSC versions 0.19.0 and 0.20.x through 0.20.0-rc3

Description The issue is related to an out-of-bounds read operation in the OpenSC library, specifically in the libopensc/card-setcos.c file during the parsing of a SETCOS file attribute. This could potentially allow an attacker to access confidential data.

Recommendations For OpenSC versions 0.19.0 and 0.20.x through 0.20.0-rc3, consider updating to a version that fixes the incorrect read operation in libopensc/card-setcos.c to prevent potential data exposure. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
