An SSE2-optimized memmove implementation for i386 in sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S in the GNU C Library (aka glibc or libc6) 2.21 through 2.27 does not correctly perform the overlapping memory check if the source memory range spans the middle of the address space, resulting in corrupt data being produced by the copy operation. This may disclose information to context-dependent attackers, or result in a denial of service, or, possibly, code execution.

Title: GNU C Library vulnerabilities
Summary: Several security issues were fixed in GNU C Library.
Florian Weimer discovered that the GNU C Library incorrectly handled
certain memory operations. A remote attacker could use this issue to cause
the GNU C Library to crash, resulting in a denial of service, or possibly
execute arbitrary code. This issue only affected Ubuntu 16.04 LTS.

## Abstract
Security metrics are not standardized, but international proposals such as the Common Vulnerability Scoring System (CVSS) for quantifying the severity of known vulnerabilities are widely used. Many CVSS aggregation mechanisms have been proposed in the literature. Nevertheless, factors related to the context of the System Under Test (SUT) are not taken into account in the aggregation process; vul

One Bad Apple Spoils the Barrel: Understanding the Security Risks Introduced by Third-Party Components in IoT Firmware
One Bad Apple Spoils the Barrel: Understanding the Security Risks Introduced by Third-Party Components in IoT Firmware
## Abstract
Currently, the development of IoT firmware heavily depends on third-party components (TPCs) to improve development efficiency. Nevertheless, TPCs are not secure, and the vulnerabilities in TPCs will influence the security of IoT firmware. Existing works pay less attention to the vulnerabilities caused by TPCs, and we still lack a comprehensive understanding of the security impact of TPC vulnerability against firmware. To fill in the knowledge gap, we design and implement , which leverages syntactical features and control-flow graph features to detect the TPCs in firmware, and then recognizes the corresponding vulnerabilities. Based on , we present the first l

Container scanning and Dependency scanning report leaked to unauthorized users
Hi GitLab Security team
### Summary
GitLab makes the container scanning and dependency scanning information available as part of a JSON endpoint for merge requests. These reports are output of the CI job and should only be displayed if the visiting user has access to CI. However, right now GitLab displays the the container scanning and dependency scanning reports regardless of this permission, making it available to whoever has access to the merge request.
For public projects, GitLab allows to restrict CI pipelines to project members only (public pipelines disabled). However, in this case, the merge request widget still renders the scanning reports result, which is the outcome of a CI pipeline.

CVE-2017-18269 glibc: memory corruption in memcpy-sse2-unaligned.S
A flaw was found in the GNU C Library (aka glibc or libc6) 2.21 through 2.27. An SSE2-optimized memmove implementation for i386 in sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S does not correctly perform the overlapping memory check if the source memory range spans the middle of the address space, resulting in corrupt data being produced by the copy operation. This may disclose information to context-dependent attackers, or result in a denial of service, or, possibly, code execution.
