This is associated with misinterpretion of an empty RPATH/RUNPATH token as the \"./\" directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very uncommon; most likely, no such program is shipped with any common Linux distribution." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "improper RPATH/RUNPATH validation" } ] } ] }, "references": { "reference_data": [ { "name": "https://sourceware.org/bugzilla/show_bug.cgi?id=22625", "refsource": "CONFIRM", "url": "https://sourceware.org/bugzilla/show_bug.cgi?id=22625" }, { "name": "102228", "refsource": "BID", "url": "http://www.securityfocus.com/bid/102228" }, { "name": "https://sourceware.org/ml/libc-alpha/2017-12/msg00528.html", "refsource": "CONFIRM", "url": "https://sourceware.org/ml/libc-alpha/2017-12/msg00528.html" }, { "name": "https://bugs.debian.org/884615", "refsource": "CONFIRM", "url": "https://bugs.debian.org/884615" }, { "name": "RHSA-2018:3092", "refsource": "REDHAT", "url": "https://access.redhat.com/errata/RHSA-2018:3092" }, { "refsource": "REDHAT", "name": "RHBA-2019:0327", "url": "https://access.redhat.com/errata/RHBA-2019:0327" } ] } }
