"CVE-2007-2027 elinks tries to load .po files from a non-absolute path

CVE-2008-7224 elinks: entity_cache static array buffer overflow
(off-by-one)

An off-by-one buffer overflow flaw was discovered in the way ELinks
handled its internal cache of string representations for HTML special
entities. A remote attacker could use this flaw to create a specially
crafted HTML file that would cause ELinks to crash or, possibly,
execute arbitrary code when rendered. (CVE-2008-7224)

It was discovered that ELinks tried to load translation files using
relative paths. A local attacker able to trick a victim into running
ELinks in a folder containing specially crafted translation files
could use this flaw to confuse the victim via incorrect translations,
or cause ELinks to crash and possibly execute arbitrary code via
embedded formatting sequences in translated messages. (CVE-2007-2027)"
