Moderate: tcltk security update. Date: Mon, 25 Feb 2008 12:11:11 -0600 Reply-To: Troy Dawson Sender: Security Errata for Scientific Linux From: Troy Dawson Subject: Security ERRATA for tcltk on SL3.x i386/x86_64 Comments: To: "This email address is being protected from spambots. You need JavaScript enabled to view it." Synopsis: Moderate: tcltk security update Issue date: 2008-02-21 CVE Names: CVE-2008-0553 CVE-2007-5378 CVE-2007-4772 An input validation flaw was discovered in Tk's GIF image handling. A code-size value read from a GIF image was not properly validated before being used, leading to a buffer overflow. A specially crafted GIF file could use this to cause a crash or, potentially, execute code with the privileges of the application using the Tk graphical toolkit. (CVE-2008-0553) A buffer overflow flaw was discovered in Tk's animated GIF image handling. An animated GIF containing an initial image smaller than subsequent images could cause a crash or, potentially, execute code with the privileges of the application using the Tk library. (CVE-2007-5378) A flaw in the Tcl regular expression handling engine was discovered by Will Drewry. This flaw, first discovered in the Tcl regular expression engine used in the PostgreSQL database server, resulted in an infinite loop when processing certain regular expressions.
