CVE-2011-0764

Publication date 31 March 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, uses an invalid pointer in conjunction with a dereference operation, which allows remote attackers to execute arbitrary code via a crafted Type 1 font in a PDF document, as demonstrated by testz.2184122398.pdf.
