According to "computerworld", Mozilla released 10 patches for three versions of its Firefox browser on Tuesday, five of which are considered critical and could be used to remotely install malicious code.
The U.S. Computer Emergency Readiness Team warned that the problems "could allow a remote attacker to execute arbitrary code, bypass intended access restrictions, cause a denial-of-service condition or obtain sensitive information."
The Mozilla products affected are Firefox 25, Firefox ESR 24.1, Firefox Extended Support Release (ESR) 17.0.10, Thunderbird 24.1, Thunderbird ESR 17.0.10, and Seamonkey 2.22.
Among the flaws fixed were several memory safety bugs in the browser engine, which is also in Mozilla's Thunderbird email client and Seamonkey, a suite of applications and web development tools.
Those bugs, tagged as update MFSA 2013-93, "showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code," according to Mozilla's advisory.
The other four critical vulnerabilities could cause potentially exploitable crashes, Mozilla said.
One of the vulnerabilities given a "high" risk rating, MFSA 2013-99, could divulge information on a computer's local system.
In August, the TOR project warned that a vulnerability in Firefox ESR may have been used to collect information on computers visiting websites configured as TOR hidden services.
