Description

The libxine development team reports that several vulnerabilities had been found in the libxine library. The first vulnerability is caused by improper checking of the src/input/libreal/real.c 'real_parse_sdp()' function. A remote attacker could exploit this by tricking an user to connect to a preparated server potentially causing a buffer overflow. Another buffer overflow had been found in the libmms library, potentially allowing a remote attacker to cause a denial of service vulnerability, and possible remote code execution through the following functions: send_command, string_utf16, get_data and get_media_packets. Other functions might be affected as well.
