A buffer overflow in Lua might allow context-dependent attackers to execute arbitrary code.
|Package||dev-lang/lua on all architectures|
|Affected versions||< 5.1.5-r4|
|Unaffected versions||>= 5.1.5-r4|
Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description.
A buffer overflow was discovered in the vararg functions in ldo.c in Lua.
Context-dependent could cause a Denial of Service condition or execute arbitrary code.
There is no known workaround at this time.
All Lua users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/lua-5.1.5-r4"
