I am trying to understand why axlDBTextBlockCompact(nil) on my test case says it can compact the text blocks down to 38, whereas I find only a total of 26 unique text block references in axlDBGetDesign()->text, axlDBGetDesign()->symbols and axlDBGetDesign()->symdefs. Where else are text blocks used besides these three?

The complexity and size of mixed-signal designs in wireless, power management, automotive, and other fast growing applications requires continued advancements in a mixed-signal verification methodology. An SoC, in these fast growing applications, incorporates a large number of analog and mixed-signal (AMS) blocks/IPs, some acquired from IP providers, some designed, often concurrently. AMS IP must be verified independently, but this is not sufficient to ensure an SoC will function properly and all scenarios of interaction among many different AMS IP blocks at full chip / SoC level must be verified thoroughly. To reduce an overall verification cycle, AMS IP and SoC verification teams must work in parallel from early stages of the design. Easier said than done! We will outline a methodology than can help.

AMS designers verify their IP meets required specifications by running a testbench they develop for standalone / out of-context verification. Typically, an AMS IP as analog-centric, hierarchal design in schematic, composed of blocks represented by transistor, HDL and behavioral description verified in Virtuoso® Analog Design Environment (ADE) using Spectre AMS Designer simulation. An SoC verification team typically uses UVM SystemVerilog testbech at full chip level where the AMS IP is represented with a simple digital or real number model running Xcelium /DMS simulation from the command line.

Ideally, AMS designers should also verify AMS IP function properly in the context of full-chip integration, but reproducing an often complex UVM SystemVerilog testbench and bringing over top-level design description to an analog-centric environment is not a simple task.

Last year, Cadence partnered with Infineon on a project with a goal to automate the reuse of a top-level testbench in AMS verification. The automation enabled AMS verification engineers to automatically configure setup for verification runs by assembling all necessary options and files from the AMS IP Virtuoso GUI and digital SoC top-level command line configurations. The benefits of this method were:

• AMS verification engineers did not need to re-create complex stimuli representing interaction of their IP at the top level
• Top-level verification stays external to the AMS IP verification environment and continues to be managed by the SoC verification team, but can be reused by the AMS IP team without manual overhead
• AMS IP is verified in-context and any inconsistencies are detected earlier in the verification process
• Improved productivity and overall verification time

NetBSD mail.local(8) local root exploit that leverages a race condition as noted in NetBSD-SA2016-006.

This Metasploit module attempts to exploit a race condition in mail.local with the SUID bit set on: NetBSD 7.0 - 7.0.1 (verified on 7.0.1), NetBSD 6.1 - 6.1.5, and NetBSD 6.0 - 6.0.6. Successful exploitation relies on a crontab job with root privilege, which may take up to 10min to execute.

NetBSD stack clash proof of concept exploit.

NetBSD Security Advisory 2004-010 - Some of the functions in /usr/src/sys/compat/ which implement execution of foreign binaries (such as Linux, FreeBSD, IRIX, OSF1, SVR4, HPUX, and ULTRIX) use argument data in unsafe ways prior to calling the kernel syscall.

Documentation for TBA, the first wardialer for the PalmOS platform. In Microsoft Word format.

TBA is the first wardialer for the PalmOS platform. Using a Palm device with a modem, you can wardial from anywhere a phone line is available - throw it in a phone can to retrieve later, toss it up in the ceiling during a security audit - the possibilities are endless.

This Metasploit module exploits a stack buffer overflow vulnerability in the handling of the TextBytesAtom records by Microsoft PowerPoint Viewer. According to Microsoft, the PowerPoint Viewer distributed with Office 2003 SP3 and earlier, as well as Office 2004 for Mac, are vulnerable. NOTE: The vulnerable code path is not reachable on versions of Windows prior to Windows Vista.

NetBSD uses the ptrace(2) system call to trace and debug other processes. The debugging process can also modify the internal registers, including the status (PSL) register, for the process being debugged. Besides the normal user-accessible flags, the VAX hardware also stores information about privilege levels and used stacks in the PSL. Those flags are only altered via the instruction REI (return from interrupt) or LDPCTX (load process context) and cannot be modified while running in "user" mode. NetBSD security page here.

Synaccess netBooter NP-02x and NP-08x version 6.8 suffer from an authentication bypass vulnerability due to a missing control check when calling the webNewAcct.cgi script while creating users. This allows an unauthenticated attacker to create an admin user account and bypass authentication giving her the power to turn off a power supply to a resource.

Energy Vault, the creator of a new way to perform utility-scale energy storage, announced that SoftBank Vision Fund (Vision Fund) invested $110 million in its Series B funding round. Energy Vault will use the funds to accelerate global deployment of its technology, which enables renewables to deliver baseload power for less than the cost of fossil fuels 24 hours a day, said the company. As part of the investment, Andreas Hansson, Partner for SoftBank Investment Advisers, will join the Energy Vault board of directors.
