FreeBSD Information Disclosure Vulnerability (CNVD-2017-37251)

FreeBSD is a set of Unix-like free operating systems in the FreeBSD project, headed by the Core Team team, and is an important branch of Unix-like systems that have evolved through BSD, 386BSD, and 4.4BSD. A security vulnerability exists in FreeBSD that stems from a program failing to properly...

BSA-2017-473

Security Advisory ID : BSA-2017-473 Component : Kernel Revision : 2.0: Final On Linux running on PowerPC hardware Power8 or later a user process can craft a signal frame and then do a sigreturn so that the kernel will take an exception interrupt, and use the r1 value from the signal frame as the...

CVE-2017-1086

FreeBSD kernel information disclosure (CVE-2017-1086): On affected releases, not all data in ptrace_lwpinfo is relevant, and the kernel may leak kernel-stack bytes to userspace via PT_LWPINFO. This is a local leak affecting FreeBSD versions listed in the CVE description, with exploitation by obse...

CVE-2017-1088: Exposure of Sensitive Information to an Unauthorized Actor

In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p4, 11.0-RELEASE-p15, 10.4-STABLE, 10.4-RELEASE-p3, and 10.3-RELEASE-p24, the kernel does not properly clear the memory of the kldfilestat structure before filling the data. Since the structure filled by the kernel is allocated on the kernel stack and...

CVE-2017-1086: Exposure of Sensitive Information to an Unauthorized Actor

FreeBSD -- Information leak in kldstat(2)

Problem Description: The kernel does not properly clear the memory of the kldfilestat structure before filling the data. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information from the kernel stack is possible. Impact: Some bytes...
