A flaw was found in Feedback. Bulk messaging in the activity's non-respondents report did not verify message recipients belonging to the set of users returned by the report.
A flaw was found in Moodle. Additional restrictions are required to avoid a remote code execution risk in calculated question types. Note: This requires the capability to add/update questions.
A flaw was found in pdfTeX. Insufficient sanitizing in the TeX notation filter resulted in an arbitrary file read risk on sites where pdfTeX is available, such as those with TeX Live installed.
