Realtek rtl8192cd Wi-Fi Driver - Auth Bypass
The rtl8192cd Wi-Fi kernel driver in the Realtek rtl819x Jungle SDK (all known versions through v3.4.14B) does not perform any access control checks on the write_mem (ioctl 0x89F5) and read_mem (ioctl 0x89F6) debug handlers, which are compiled into production builds via the unconditionally defined _IOCTL_DEBUG_CMD_ macro in 8192cd_cfg.h

Linux Kernel - Use-After-Free in proc_readdir_de via Concurrent getdents and unregister_netdevice
In the Linux kernel, the following vulnerability has been resolved:
fs/proc: fix uaf in proc_readdir_de()
Pde is erased from subdir rbtree through rb_erase(), but not set the node
to EMPTY, which may result in uaf access. We should use RB_CLEAR_NODE()
set the erased node to EMPTY, then pde_subdir_next() will return NULL to
avoid uaf access.
We found an uaf issue while using stress-ng testing, need to run testcase
getdent and tun in the same time. The steps of the issue is as follows:
1) use getdent to traverse dir /proc/pid/net/dev_snmp6/, and current
pde is tun3;
2) in the [time windows] unregister netdevice tun3 and tun2, and erase
them from rbtree. erase tun3 first, and then erase tun2. the
pde(tun2) will be released to slab;
3) continue to getdent process, then pde_subdir_next() will return
pde(tun2) which is released, it will case uaf access.

freeFTPd < 1.0.9 - Stack-Based Buffer Overflow via Long USER Command
Stack-based buffer overflow in freeFTPd before 1.0.9 with Logging enabled, allows remote attackers to cause a denial of service (application crash), and possibly execute arbitrary code, via a long USER command.
Essentia Web Server 2.1 - Buffer Overflow via Long URL
Buffer overflow in Essentia Web Server 2.1 allows remote attackers to cause a denial of service, and possibly execute arbitrary code, via a long URL.
CA License Client and Server 0.1.0.15 - Multiple Buffer Overflow via GCR Request and GETCONFIG Packet
Multiple buffer overflows in Computer Associates (CA) License Client and Server 0.1.0.15 allow remote attackers to execute arbitrary code via (1) certain long fields in the Checksum item in a GCR request, (2) a long IP address, hostname, or netmask values in a GCR request, (3) a long last parameter in a GETCONFIG packet, or (4) long values in a request with an invalid format.
BakBone NetVault <7 - Buffer Overflow
Multiple buffer overflows in BakBone NetVault 6.x and 7.x allow (1) remote attackers to execute arbitrary code via a modified computer name and length that leads to a heap-based buffer overflow, or (2) local users to execute arbitrary code via a long Name entry in the configure.cfg file.
NetZero < 3.0 - Weak Encryption of User Login Information
NetZero 3.0 and earlier uses weak encryption for storing a user's login information, which allows a local user to decrypt the password.
Microsoft Windows SMB Driver Ioctl Local Privilege Escalation
The Server Message Block (SMB) driver (MRXSMB.SYS) in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 and earlier allows local users to execute arbitrary code by calling the MrxSmbCscIoctlOpenForCopyChunk function with the METHOD_NEITHER method flag and an arbitrary address, possibly for kernel memory, aka the "SMB Driver Elevation of Privilege Vulnerability."
Windows - Local Privilege Escalation via EPATHOBJ::pprFlattenRec Pointer Initialization
The EPATHOBJ::pprFlattenRec function in win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, and Windows Server 2012 does not properly initialize a pointer for the next object in a certain list, which allows local users to obtain write access to the PATHRECORD chain, and consequently gain privileges, by triggering excessive consumption of paged memory and then making many FlattenPath function calls, aka "Win32k Read AV Vulnerability."
CVSS 7.8
Microsoft Windows Contacts - Untrusted Search Path and DLL Hijacking via Trojan Horse wab32res.dll
Untrusted search path vulnerability in Microsoft Windows Contacts allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse wab32res.dll that is located in the same folder as a .contact, .group, .p7c, .vcf, or .wab file.

Microsoft Windows 2000 through SP4 and XP through SP2 - Privilege Escalation via GDI Kernel Structure Memory Remapping
The Graphics Rendering Engine in Microsoft Windows 2000 through 2000 SP4 and Windows XP through SP2 maps GDI Kernel structures on a global shared memory section that is mapped with read-only permissions, but can be remapped by other processes as read-write, which allows local users to cause a denial of service (memory corruption and crash) and gain privileges by modifying the kernel structures.
