Descriptions

Multiple integer overflow and buffer overflow issues were discovered in spice-client's handling of LZ compressed frames. A malicious server could cause the client to crash or, potentially, execute arbitrary code.

Se han descubierto múltiples problemas de desbordamiento de enteros y desbordamiento de búfer en el manejo de spice-client de los frames comprimidos LZ. Un servidor malicioso podría provocar que el cliente se cierre inesperadamente o ejecute código arbitrario.

The spice-gtk packages provide a GIMP Toolkit widget for Simple Protocol for Independent Computing Environments clients. Both Virtual Machine Manager and Virtual Machine Viewer can make use of this widget to access virtual machines using the SPICE protocol. The libgovirt packages contain a library that allows applications to use the oVirt Representational State Transfer API to list virtual machines managed by an oVirt instance. The library is also used to get the connection parameters needed to establish a connection to the VMs using Simple Protocol For Independent Computing Environments or Virtual Network Computing . Issues addressed include a buffer overflow vulnerability.
