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

opensc: stack-based buffer overflow in sc_pkcs15emu_gemsafeGPK_init

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.

opensc: heap-based buffer overflow in sc_oberthur_read_file

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

opensc: memory leak in sc_context_create in ctx.c in libopensc

sc_context_create in ctx.c in libopensc in OpenSC 0.19.0 has a memory leak, as demonstrated by a call from eidenv.

opensc: Double free in coolkey_free_private_data in libopensc/card-coolkey.c

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.

opensc: Improper handling of buffer limits for CAC certificates

An issue was discovered in OpenSC through 0.19.0 and 0.20.x through 0.20.0-rc3. libopensc/card-cac1.c mishandles buffer limits for CAC certificates.

opensc: incorrect free operation in sc_pkcs15_decode_prkdf_entry in libopensc/pkcs15-prkey.c

An issue was discovered in OpenSC through 0.19.0 and 0.20.x through 0.20.0-rc3. libopensc/pkcs15-prkey.c has an incorrect free operation in sc_pkcs15_decode_prkdf_entry.

opensc: Incorrect read operation during parsing of a SETCOS file attribute

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.

An issue was discovered in the pam_p11 component 0.2.0 and 0.3.0 for OpenSC. If a smart card creates a signature with a length longer than 256 bytes, this triggers a buffer overflow. This may be the case for RSA keys with 4096 bits depending on the signature scheme.

opensc: Out-of-bounds access of an ASN.1 Octet string in asn1_decode_entry in libopensc/asn1.c

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.

opensc: Out-of-bounds access of an ASN.1 Bitstring in decode_bit_string in libopensc/asn1.c

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.

opensc: Out of bounds reads handling responses from smartcards

Various out of bounds reads when handling responses in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to potentially crash the opensc library using programs.

opensc: Infinite recusrion handling responses from IAS-ECC cards in card-iasecc.c:iasecc_select_file()

Endless recursion when handling responses from an IAS-ECC card in iasecc_select_file in libopensc/card-iasecc.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to hang or crash the opensc library using programs.

opensc: Double free handling responses from HSM Cards in pkcs15-sc-hsm.c:sc_pkcs15emu_sc_hsm_init()

A double free when handling responses from an HSM Card in sc_pkcs15emu_sc_hsm_init in libopensc/pkcs15-sc-hsm.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.
