CVE-2007-6109

Publication date 7 December 2007

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Stack-based buffer overflow in emacs allows user-assisted attackers to cause a denial of service (application crash) and possibly have unspecified other impact via a large precision value in an integer format string specifier to the format function, as demonstrated via a certain "emacs -batch -eval" command line.
