DEBIAN-CVE-2016-2851

Integer overflow in proto.c in libotr before 4.1.1 on 64-bit platforms allows remote attackers to cause a denial of service memory corruption and application crash or execute arbitrary code via a series of large OTR messages, which triggers a heap-based buffer overflow...

The vulnerability of Nettle’s cryptographic library allows attackers to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of x8664/ecc-384-modp.asm in the Nettle cryptographic library is related to errors in cryptographic transformations. Exploiting this vulnerability could allow a remote attacker to compromise the confidentiality, integrity, and accessibility of the protected information...

I/O port access privilege escalation in x86-64 Linux

ISSUE DESCRIPTION IRET and POPF do not modify EFLAGS.IOPL when executed by code at a privilege level other than zero. Since PV Xen guests run at privilege level 3 for 64-bit ones; 32-bit ones run at privilege level 1, to compensate for this the context switching of EFLAGS.IOPL requires the guest ...

Medium: kernel

Issue Overview: When running as a Xen 64-bit PV guest, user mode processes not supposed to be able to access I/O ports may be granted such permission, potentially resulting in one or more of in-guest privilege escalation, guest crashes Denial of Service, or in-guest information leaks. CVE-2016-31...
