CVE-2014-0211

Published: 13 May 2014

Multiple integer overflows in the (1) fs_get_reply, (2) fs_alloc_glyphs, and (3) fs_read_extent_info functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 allow remote font servers to execute arbitrary code via a crafted xfs reply, which triggers a buffer overflow.

Notes

AuthorNote
mdeslaur
trusty and later are built with --disable-fc, so this shouldn't
be an issue. Adding patch anyway for completeness' sake.
