This may affect data integrity in certain iconv() use cases. NOTE: the vendor states \"the bug cannot be invoked through user input and requires iconv to be invoked with a NULL inbuf, which ought to require a separate application bug to do so unintentionally. Hence there's no security impact to the bug.\"" } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "url": "https://sourceware.org/bugzilla/show_bug.cgi?id=28524", "refsource": "MISC", "name": "https://sourceware.org/bugzilla/show_bug.cgi?id=28524" }, { "refsource": "MISC", "name": "https://sourceware.org/git/?p=glibc.git;a=commit;h=ff012870b2c02a62598c04daa1e54632e020fd7d", "url": "https://sourceware.org/git/?p=glibc.git;a=commit;h=ff012870b2c02a62598c04daa1e54632e020fd7d" }, { "refsource": "MISC", "name": "https://blog.tuxcare.com/vulnerability/vulnerability-in-iconv-identified-by-tuxcare-team-cve-2021-43396", "url": "https://blog.tuxcare.com/vulnerability/vulnerability-in-iconv-identified-by-tuxcare-team-cve-2021-43396" }, { "url": "https://www.oracle.com/security-alerts/cpujul2022.html" } ] } }
