A flaw has been found in OpenSC up to 0.26.1. This affects the function test_kpgen_certwrite of the file src/tools/pkcs11-tool.c of the component pkcs11-tool Key Generation Module. This manipulation causes buffer overflow. The attack is possible to be carried out remotely. The complexity of an attack is rather high. It is indicated that the exploitability is difficult. The exploit has been published and may be used. Patch name: 814f745b3b6d100295f65f1935edd33d520d33ab. It is recommended to apply a patch to fix this issue.
A flaw was found in OpenSC, specifically within the pkcs11-tool Key Generation Module. This vulnerability, located in the test_kpgen_certwrite function, is a buffer overflow that can be triggered remotely. A remote attacker could exploit this flaw, potentially leading to information disclosure, data corruption, or denial of service.
Отчет
This Moderate impact flaw in OpenSC's pkcs11-tool Key Generation Module could lead to information disclosure, data corruption, or denial of service. While the vulnerability is remotely triggerable, its high attack complexity and difficult exploitability, requiring user interaction with a specially crafted input to the pkcs11-tool utility, limit its immediate risk in typical Red Hat deployments.
