As a temporary workaround, restrict the processing of jpeg files to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Dropbox lepton version 1.0 **Description** The issue allows remote attackers to cause a denial of service, resulting in a segmentation fault, by providing a crafted jpeg file. This is due to a problem in the setup imginfo jpg function located in lepton/jpgcoder.cc. **Recommendations** For version 1.0, consider avoiding the use of the setup imginfo jpg function until a patch is available. As a temporary workaround, restrict the processing of jpeg files from untrusted sources to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Android versions 5.0.2, 5.1.1, 6.0, 6.0.1, 7.0 **Description** A remote code execution issue in the Framesequence library could allow an attacker to execute arbitrary code using a specially crafted file. This issue is related to inadequate access control in the library. The problem can be exploited by a remote attacker to execute code in the context of an unprivileged process. **Recommendations** For Android versions 5.0.2, 5.1.1, 6.0, 6.0.1, 7.0, at the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 4.8.10 **Description** The issue is related to the mishandling of skb truncation in the TCP stack, which can be exploited by local users to cause a denial of service, resulting in a system crash.
