Perl. This issue was addressed with improved checks.
Perl before 5.30.3 has an integer overflow related to mishandling of a "PLregkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection.
In Vim before 8.1.0881, users can circumvent the rvim restricted mode and execute arbitrary OS commands via scripting interfaces (e.g., Python, Ruby, or Lua).
An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds read in ImfOptimizedPixelReading.h.
An issue was discovered in OpenEXR before 2.4.1. Because of integer overflows in CompositeDeepScanLine::Data::handleDeepFrameBuffer and readSampleCountForLineBlock, an attacker can write to an out-of-bounds pointer.
An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds read during RLE uncompression in rleUncompress in ImfRle.cpp.
