Deserialization of Untrusted Data

Overview ply is a Python Lex & Yacc Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the picklefile parameter in the yacc function. An attacker can execute arbitrary code by supplying a specially crafted pickle file that is deserialized without validation...

CVE-2025-56005: Deserialization of Untrusted Data

An undocumented and unsafe feature in the PLY Python Lex-Yacc library 3.11 allows Remote Code Execution RCE via the picklefile parameter in the yacc function. This parameter accepts a .pkl file that is deserialized with pickle.load without validation. Because pickle allows execution of embedded...

OESA-2023-1033 byacc security update

Berkeley Yacc is an LALR1 parser generator. Berkeley Yacc has been made as compatible as possible with AT&T Yacc. Berkeley Yacc can accept any input specification that conforms to the AT&T Yacc documentation. Specifications that take advantage of undocumented features of AT&T Yacc will probably b...

[SECURITY] Fedora 35 Update: nex-20210330-2.fc35

Nex is a lexer similar to Lex/Flex that: 1 generates Go code instead of C code, 2 integrates with Go's Yacc instead of YACC/Bison, 3 supports UTF-8, and 4 supports nested structural regular expressions...

[SECURITY] Fedora 27 Update: global-6.5.7-4.fc27

GNU GLOBAL is a source code tag system that works the same way across diverse environments. It supports C, C++, Yacc, Java, PHP and assembler source code...

[SECURITY] Fedora 24 Update: flex-2.6.0-2.fc24

The flex program generates scanners. Scanners are programs which can recognize lexical patterns in text. Flex takes pairs of regular expressions and C code as input and generates a C source file as output. The output file is compiled and linked with a library to produce an executable. The...
