Descriptions

OpenSSL before 0.9.8m does not check for a NULL return value from bn_wexpand function calls in (1) crypto/bn/bn_div.c, (2) crypto/bn/bn_gf2m.c, (3) crypto/ec/ec2_smpl.c, and (4) engines/e_ubsec.c, which has unspecified impact and context-dependent attack vectors.

OpenSSL en versiones anterioes a v0.9.8m cuando recibe un valor de retorno NULL de la funcion bn_wexpand hace una llamada a (1) crypto/bn/bn_div.c, (2) crypto/bn/bn_gf2m.c, (3) crypto/ec/ec2_smpl.c, y (4) engines/e_ubsec.c, lo que tiene un impacto inespecifico y vectores de ataque dependientes del contexto.
