Red Hat Bugzilla – Bug 675143
CVE-2011-0058 Mozilla memory corruption during text run construction (MFSA 2011-07)
Last modified: 2015-08-19 05:04:33 EDT
Alex Miller reported that when very long strings were constructed
and inserted into an HTML document, the browser would incorrectly
construct the layout objects used to display the text.
Under such conditions an incorrect length would be calculated for
a text run resulting in too small of a memory buffer being allocated
to store the text.
This issue could be used by an attacker to write data past the end
of the buffer and execute malicious code on a victim's computer.
This is now public:
This issue has been addressed in following products:
Red Hat Enterprise Linux 4
Red Hat Enterprise Linux 5
Red Hat Enterprise Linux 6
