Descriptions

Memory leak in the zlib_stateful_init function in crypto/comp/c_zlib.c in libssl in OpenSSL 0.9.8f through 0.9.8h allows remote attackers to cause a denial of service (memory consumption) via multiple calls, as demonstrated by initial SSL client handshakes to the Apache HTTP Server mod_ssl that specify a compression algorithm.

Fuga de memoria en la Función zlib_stateful_init en crypto/comp/c_zlib.c en libssl en OpenSSL v0.9.8f a la 0.9.8h, permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de múltiples llamadas, como se ha demostrado mediante una negociación cliente SSL inicial al servidor HTTP Apache (mod_ssl) que especifica un algoritmo de compresión.
