Title
Cisco StarOS Denial of Service Vulnerability
Summary
A vulnerability in the internal packet-processing functionality of the Cisco StarOS operating system running on virtual platforms could allow an unauthenticated, remote attacker to cause an affected device to stop processing traffic, resulting in a denial of service (DoS) condition. The vulnerability is due to a logic error that may occur under specific traffic conditions. An attacker could exploit this vulnerability by sending a series of crafted packets to an affected device. A successful exploit could allow the attacker to prevent the targeted service interface from receiving any traffic, which would lead to a DoS condition on the affected interface. The device may have to be manually reloaded to recover from exploitation of this vulnerability.

Summary
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 9.0.0.29935. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of U3D files. The issue results from the lack of proper initialization of a pointer prior to accessing it. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-5431.

Title
mingw-w64 version 5.0.4 by default produces executables that opt in to ASLR, but are not compatible with ASLR
Summary
mingw-w64 version 5.0.4 by default produces executables that opt in to ASLR, but are not compatible with ASLR. ASLR is an exploit mitigation technique used by modern Windows platforms. For ASLR to function, Windows executables must contain a relocations table. Despite containing the "Dynamic base" PE header, which indicates ASLR compatibility, Windows executables produced by mingw-w64 have the relocations table stripped from them by default. This means that executables produced by mingw-w64 are vulnerable to return-oriented programming (ROP) attacks. Windows executables generated by mingw-w64 claim to be ASLR compatible, but are not. Vulnerabilities in such executables are more easily exploitable as a result.
Severity
No CVSS data available.

Details
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix uninitialized pointer free in add_inode_ref()
The add_inode_ref() function does not initialize the "name" struct when it is declared. If any of the following calls to "read_one_inode() returns NULL,
dir = read_one_inode(root, parent_objectid);
if (!dir) {
ret = -ENOENT;
goto out;
}
inode = read_one_inode(root, inode_objectid);
if (!inode) {
ret = -EIO;
goto out;
}
then "name.name" would be freed on "out" before being initialized.
out: ... kfree(name.name);
This issue was reported by Coverity with CID 1526744.
