CVE-ID : CVE-2020-15888 CVE-2020-15889
Package : lua
Type : arbitrary code execution
Remote : Yes
Link : https://security.archlinux.org/AVG-1207
The package lua before version 5.4.1-1 is vulnerable to arbitrary code
execution.
Upgrade to 5.4.1-1.
The problems have been fixed upstream in version 5.4.1.
None.
Lua through 5.4.0 mishandles the interaction between stack resizes and
garbage collection, leading to a heap-based buffer overflow, heap-based
buffer over-read, or use-after-free.
Lua through 5.4.0 has a getobjname heap-based buffer over-read because
youngcollection in lgc.c uses markold for an insufficient number of
list members.
A remote attacker is capable of executing arbitrary code on the
affected host.
