[SECURITY] Fedora 33 Update: lua-5.4.0-7.fc33

Lua is a powerful light-weight programming language designed for extending applications. Lua is also frequently used as a general-purpose, stand-alone language. Lua is free software. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and...

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 allows a stack redzone cross in luaO_pushvfstring because a protection mechanism wrongly calls luaD_callnoyield twice in a row.

...

Lua 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.

...

Lua 5.3.5 has a use-after-free in lua_upvaluejoin in lapi.c. For example a crash outcome might be achieved by an attacker who is able to trigger a debug.upvaluejoin call in which the arguments have certain relationships.

Amazon Linux 2 : lua53 (ALAS-2020-1492)

The version of lua53 installed on the remote host is prior to 5.3.5-7. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1492 advisory. ldebug.c in Lua 5.4.0 allows a negation overflow and segmentation fault in getlocal and setlocal, as demonstrated by getlocal3,2^31...

GHSA-QV8Q-V995-72GR personnummer/csharp vulnerable to Improper Input Validation

This vulnerability was reported to the personnummer team in June 2020. The slow response was due to locked ownership of some of the affected packages, which caused delays to update packages prior to disclosure. The vulnerability is determined to be low severity. Impact This vulnerability impacts...
