CVE-2009-3050
Buffer overflow in the set_page_size function in util.cxx in HTMLDOC 1.8.27 and earlier allows context-dependent attackers to execute arbitrary code via a long MEDIA SIZE comment.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Buffer overflow in the set_page_size function in util.cxx in HTMLDOC 1.8.27 and earlier allows context-dependent attackers to execute arbitrary code via a long MEDIA SIZE comment. NOTE: it was later reported that there were additional vectors in htmllib.cxx and ps-pdf.cxx using an AFM font file with a long glyph name, but these vectors do not cross privilege boundaries.
