pptpgre.c in PoPToP Point to Point Tunneling Server (pptpd) before 1.3.4 allows remote attackers to cause a denial of service (PPTP connection tear-down) via (1) GRE packets with out-of-order sequence numbers or (2) certain GRE packets that are processed using a wrong pointer and improperly dequeued.
The in_decimal::set function in item_cmpfunc.cc in MySQL before 5.0.40, and 5.1 before 5.1.18-beta, allows context-dependent attackers to cause a denial of service (crash) via a crafted IF clause that results in a divide-by-zero error and a NULL pointer dereference.
Multiple heap-based buffer overflows in the cirrus_invalidate_region function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow.
QEMU 0.8.2 allows local users to crash a virtual machine via the divisor operand to the aam instruction, as demonstrated by "aam 0x0," which triggers a divide-by-zero error.
Untrusted search path vulnerability in PostgreSQL before 7.3.19, 7.4.x before 7.4.17, 8.0.x before 8.0.13, 8.1.x before 8.1.9, and 8.2.x before 8.2.4 allows remote authenticated users, when permitted to call a SECURITY DEFINER function, to gain the privileges of the function owner, related to "search_path settings."
A typo in Linux kernel 2.6 before 2.6.21-rc6 and 2.4 before 2.4.35 causes RTA_MAX to be used as an array size instead of RTN_MAX, which leads to an "out of bound access" by the (1) dn_fib_props (dn_fib.c, DECNet) and (2) fib_props (fib_semantics.c, IPv4) functions.
The telnet daemon (telnetd) in MIT krb5 before 1.6.1 allows remote attackers to bypass authentication and gain system access via a username beginning with a '-' character, a similar issue to CVE-2007-0882.
