Produktbeschreibung: Perl Compatible Regular Expressions (PCRE) ist eine Programmbibliothek zur Auswertung und Anwendung von regulären Ausdrücken.
Angriff: Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in PCRE2 (Perl Compatible Regular Expressions) ausnutzen, um einen Denial of Service Angriff durchzuführen.
Betroffene Betriebssysteme: - UNIX
- Linux
- Appliance
In PCRE2 (Perl Compatible Regular Expressions) existieren mehrere Schwachstellen. Die Fehler bestehen aufgrund von mehreren Out-of-Bound-Reads in den Funktionen "compile_xclass_matchingpath()" und "get_recurse_data_length()" der Datei "pcre2_jit_compile.c". Ein entfernter, anonymer Angreifer kann diese Schwachstellen ausnutzen, um einen Denial-of-Service-Zustand zu verursachen.
