Message-ID: <20030126081334.17094.qmail@web10411.mail.yahoo.com> From: woot_woot_root at yahoo.co.uk (Faulty) Subject: format strings vulns in /bin/login and /usr/bin/passwd Hello while doing a scan for format strings vulns on util-linux package it came back with the following results. ./login.c:398 FUNC fprintf ./login.c:425 FUNC fprintf ./login.c:597 FUNC fprintf ./login.c:614 FUNC fprintf ./login.c:775 FUNC printf ./login.c:796 FUNC fprintf ./login.c:800 FUNC fprintf ./login.c:1109 FUNC syslog ./login.c:1119 FUNC printf ./login.c:1127 FUNC fprintf ./login.c:1183 FUNC fprintf ./login.c:1190 FUNC fprintf ./login.c:1201 FUNC fprintf ./passwd.c:161 FUNC printf ./passwd.c:174 FUNC printf ./passwd.c:175 FUNC printf ./passwd.c:176 FUNC printf ./passwd.c:181 FUNC printf ./passwd.c:186 FUNC printf ./passwd.c:197 FUNC printf ./passwd.c:204 FUNC printf ./passwd.c:222 FUNC printf ./passwd.c:223 FUNC printf ./passwd.c:277 FUNC fprintf ./passwd.c:316 FUNC printf ./passwd.c:323 FUNC printf ./passwd.c:331 FUNC printf ./passwd.c:401 FUNC syslog ./passwd.c:410 FUNC printf ./passwd.c:414 FUNC printf ./passwd.c:420 FUNC printf There is also a few other on other programs but i thought these 2 would be most important since passwd is suid and login could be exploited remotly. I am not very experianced in format strings any help/commets would be great. Would these be able to get exploited? Regards Faulty@....net www.b0f.net --------------------------------- With Yahoo!
