CVE-2013-1667 – perl: DoS in rehashing code

https://notcve.org/view.php?id=CVE-2013-1667

The rehash mechanism in Perl 5.8.2 through 5.16.x allows context-dependent attackers to cause a denial of service (memory consumption and crash) via a crafted hash key. El mecanismo de rehash en Perl v5.8.2 a través v5.16.x permite a atacantes dependientes de contexto provocar una denegación de servicio (consumo de memoria y caída) mediante una tecla de almohadilla diseñada. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=702296 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10735 http://lists.apple.com/archives/security-announce/2013/Oct/msg00004.html http://marc.info/?l=bugtraq&m=137891988921058&w=2 http://osvdb.org/90892 http://perl5.git.perl.org/perl.git/commitdiff/6e79fe5 http://perl5.git.perl.org/perl.git/commitdiff/9d83adc http://perl5.git.perl.org/perl.git&# • CWE-399: Resource Management Errors •

CVE-2012-6329 – Foswiki MAKETEXT - Remote Command Execution

https://notcve.org/view.php?id=CVE-2012-6329

The _compile function in Maketext.pm in the Locale::Maketext implementation in Perl before 5.17.7 does not properly handle backslashes and fully qualified method names during compilation of bracket notation, which allows context-dependent attackers to execute arbitrary commands via crafted input to an application that accepts translation strings from users, as demonstrated by the TWiki application before 5.1.3, and the Foswiki application 1.0.x through 1.0.10 and 1.1.x through 1.1.6. La función _compile en Maketext.pm en la implementación de Locale::Maketext en Perl anteriores a v5.17.7 no gestionan de forma adecuada los slash cruzados (\) y lo nombres de métodos cualificados durante la compilación o notación de comillas, lo que permite a atacantes dependiendo del contexto a ejecutar comandos a través de entradas manipulados sobre una aplicación que acepta la traslación de cadenas desde usuarios, como se demostró por la aplicación TWiki anteriores a v5.1.3, y la aplicación Foswiki v1.0.x hasta v1.0.10 y v1.1.x hasta v1.1.6. • https://www.exploit-db.com/exploits/23580 https://www.exploit-db.com/exploits/23579 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=695224 http://code.activestate.com/lists/perl5-porters/187746 http://code.activestate.com/lists/perl5-porters/187763 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10735 http://openwall.com/lists/oss-security/2012/12/11/4 http://perl5.git.perl.org/perl.git/blob/HEA • CWE-94: Improper Control of Generation of Code ('Code Injection') •

CVE-2012-5195 – perl: heap buffer overrun flaw may lead to arbitrary code execution

https://notcve.org/view.php?id=CVE-2012-5195

Heap-based buffer overflow in the Perl_repeatcpy function in util.c in Perl 5.12.x before 5.12.5, 5.14.x before 5.14.3, and 5.15.x before 15.15.5 allows context-dependent attackers to cause a denial of service (memory consumption and crash) or possibly execute arbitrary code via the 'x' string repeat operator.

CVE-2011-2939 – Perl decode_xs heap-based buffer overflow

https://notcve.org/view.php?id=CVE-2011-2939

Off-by-one error in the decode_xs function in Unicode/Unicode.xs in the Encode module before 2.44, as used in Perl before 5.15.6, might allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Unicode string, which triggers a heap-based buffer overflow.
