Debian Linux Security Advisory 1273-1

Posted Mar 28, 2007

Authored by Debian | Site debian.org

Debian Security Advisory 1273-1 - Several vulnerabilities have been discovered in nas, the Network Audio System. A stack-based buffer overflow in the accept_att_local function in server/os/connection.c in nas allows remote attackers to execute arbitrary code via a long path slave name in a USL socket connection. Integer overflow in the ProcAuWriteElement function in server/dia/audispatch.c allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large max_samples value. The AddResource function in server/dia/resource.c allows remote attackers to cause a denial of service (server crash) via a nonexistent client ID. Array index error allows remote attackers to cause a denial of service (crash) via (1) large num_action values in the ProcAuSetElements function in server/dia/audispatch.c or (2) a large inputNum parameter to the compileInputs function in server/dia/auutil.c. The ReadRequestFromClient function in server/os/io.c allows remote attackers to cause a denial of service (crash) via multiple simultaneous connections, which triggers a NULL pointer dereference.
