Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3463 advisory.

- sc_context_create in ctx.c in libopensc in OpenSC 0.19.0 has a memory leak, as demonstrated by a call from eidenv. (CVE-2019-6502)

- A heap use after free issue was found in Opensc before version 0.22.0 in sc_file_valid. (CVE-2021-42779)

- A use after return issue was found in Opensc before version 0.22.0 in insert_pin function that could potentially crash programs using the library. (CVE-2021-42780)

- Heap buffer overflow issues were found in Opensc before version 0.22.0 in pkcs15-oberthur.c that could potentially crash programs using the library. (CVE-2021-42781)

- Stack buffer overflow issues were found in Opensc before version 0.22.0 in various places that could potentially crash programs using the library. (CVE-2021-42782)

- A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15 cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context.
The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. In cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is possible. (CVE-2023-2977)

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

Solution

Upgrade the opensc packages.

For Debian 10 buster, these problems have been fixed in version 0.19.0-1+deb10u2.
