An Anti-Terrorism Court (ATC) in Rawalpindi last week convicted additional inspector general Saud Aziz and Senior Superintendent of police Khurram Shehzad for negligence and security lapses and sentenced them to 17 years in prison.
The two have challenged the judgement in the Rawalpindi bench of the Lahore High Court, a court official said.
Both the officers contented in the appeal that they had provided adequate security to Bhutto who was killed in Rawalpindi, the official added.
The officers asked the court to overturn the verdict, saying the decision was full of contradictions as the court set free the five prime suspects who were kept in jail since 2008 when they were arrested.

They said the prosecution did not have any solid evidence against the accused.
It, however, declared former dictator Pervez Musharraf a fugitive and ordered authorities to seize his properties.
A joint investigation team had implicated Musharraf in the case, saying his government did not provide adequate security to Bhutto during the rally despite her repeated requests.
It is not known when the high court will take up the appeal for hearing.
