The build package before 20171128 did not check directory names during extraction of build results that allowed untrusted builds to write outside of the target system,allowing escape out of buildroots.

The tcpmssmanglepacket function in net/netfilter/xtTCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xtTCPMSS in an iptables action.

DISPUTED LibTIFF 4.0.8 has multiple memory leak vulnerabilities, which allow attackers to cause a denial of service (memory consumption), as demonstrated by tifopen.c, tiflzw.c, and tifaux.c. NOTE: Third parties were unable to reproduce the issue.
