Mandriva Linux Security Advisory - A stack-based buffer overflow in the random number generator could allow local root users to cause a denial of service or gain privileges by setting the default wakeup threshold to a value greater than the output pool size. The lcd_write function did not limit the amount of memory used by a caller, which allows local users to cause a denial of service (memory consumption). The decode_choice function allowed remote attackers to cause a denial of service (crash) via an encoded out-of-range index value for a choice field which triggered a NULL pointer dereference. The Linux kernel allowed local users to send arbitrary signals to a child process that is running at higher privileges by causing a setuid-root parent process to die which delivered an attacker-controlled parent process death signal (PR_SET_PDEATHSIG). The aac_cfg_openm and aac_compat_ioctl functions in the SCSI layer ioctl patch in aacraid did not check permissions for ioctls, which might allow local users to cause a denial of service or gain privileges. The IA32 system call emulation functionality, when running on the x86_64 architecture, did not zero extend the eax register after the 32bit entry path to ptrace is used, which could allow local users to gain privileges by triggering an out-of-bounds access to the system call table using the %RAX register.
