Descriptions

Multiple heap-based buffer overflows in the rc4 (1) encryption (aka exsltCryptoRc4EncryptFunction) and (2) decryption (aka exsltCryptoRc4DecryptFunction) functions in crypto.c in libexslt in libxslt 1.1.8 through 1.1.24 allow context-dependent attackers to execute arbitrary code via an XML file containing a long string as "an argument in the XSL input."

Múltiples desbordamientos de búfer basados en montículo en las funciones rc4 de (1) cifrado (aka exsltCryptoRc4EncryptFunction) y (2) descifrado (aka exsltCryptoRc4DecryptFunction) en crypto.c en libexslt en libxslt 1.1.8 hasta 1.1.24 permite a atacantes dependientes de contexto ejecutar código de su elección a través de un fichero XML que contiene una larga cadena de caracteres como "un argumento en la entrada XSL."

It was discovered that long transformation matches in libxslt could overflow. If an attacker were able to make an application linked against libxslt process malicious XSL style sheet input, they could execute arbitrary code with user privileges or cause the application to crash, leading to a denial of service. Chris Evans discovered that the RC4 processing code in libxslt did not correctly handle corrupted key information. If a remote attacker were able to make an application linked against libxslt process malicious XML input, they could crash the application, leading to a denial of service.
