Christey" <coley@...us.mitre.org> To: oss-security@...ts.openwall.com, me@...ji.com Subject: Re: CVE Request: gif2png: command-line buffer overflow problem This type of error may happen when executing from a shell, but not necessarily *every* shell, and not when shell execution is bypassed e.g. when using exec()... so the vulnerable program might still execute. - Steve On Mon, 22 Nov 2010, Benji wrote: > "File name too long" > > ------Original Message------ > From: Dan Rosenberg > To: oss-security@...ts.openwall.com > ReplyTo: oss-security@...ts.openwall.com > Subject: Re: [oss-security] CVE Request: gif2png: command-line buffer overflow problem > Sent: Nov 22, 2010 00:19 > > How could this possibly be exploited?
