Ubuntu Security Notice 5647-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.

An attacker can upload a malicious PHP code file via the profile photo functionality by leveraging a path traversal vulnerability in the users['photop_preview'] delete photo feature thus allowing bypass of .htaccess protection. NOTE: this issue exists because of an incomplete fix for CVE-2015-3884.

This tool packs up to 4KB of compressed shellcode into an executable binary, near-instantly. The output file will always have the same MD5 hash: 3cebbe60d91ce760409bbe513593e401. Currently, only Linux x86-64 is supported. It would be trivial to port this technique to other platforms, although each version would end up with a different MD5.
