Using Speakeasy Emulation Framework Programmatically to Unpack Malware

Andrew Davis recently announced the public release of his new Windows emulation framework named Speakeasy. While the introductory blog post focused on using Speakeasy as an automated malware sandbox of sorts, this entry will highlight another powerful use of the framework: automated malware...

USN-4650-1 qemu vulnerabilities

Alexander Bulekov discovered that QEMU incorrectly handled SDHCI device emulation. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code on the host. In the default installation, when QEMU is used with libvir...

kernel: out of bounds write in function i2c_smbus_xfer_emulated in drivers/i2c/i2c-core-smbus.c

An out of bounds OOB memory access flaw was found in i2csmbusxferemulated in drivers/i2c/i2c-core-smbus.c in I2C subsystem. A read request for length data-block0 greater than 'I2CSMBUSBLOCKMAX + 1' may cause underlying I2C driver write out of array's boundary. This could allow a local attacker wi...
