Name of the Vulnerable Software and Affected Versions OpenSC versions prior to 0.19.0-rc1

Description A single byte buffer overflow occurs when handling responses from an esteid Card in the sc pkcs15emu esteid init function in libopensc/pkcs15-esteid.c. This issue could be exploited by attackers who can supply crafted smartcards, potentially causing a denial of service (application crash) or having other unspecified impacts.

Recommendations For versions prior to 0.19.0-rc1, update to version 0.19.0-rc1 or later to resolve the issue. As a temporary workaround, consider restricting the use of crafted smartcards to minimize the risk of exploitation.
