Integer underflow in rxRPC.dll in the LGServer service in the server in CA ARCserve Backup for Laptops and Desktops 11.0 through 11.5 allows remote attackers to execute arbitrary code or cause a denial of service via a crafted message that triggers a buffer overflow.

Directory traversal vulnerability in caloggerd in CA BrightStor ARCServe Backup 11.0, 11.1, and 11.5 allows remote attackers to append arbitrary data to arbitrary files via directory traversal sequences in unspecified input fields, which are used in log messages. NOTE: this can be leveraged for code execution in many installation environments by writing to a startup file or configuration file.
