Ensure That the umask Value Is Correct

The umask value is the mask for default file or directory permissions. When a file or directory is created, its default permission is set to 777 minus the umask value. For a file, its execute permission is also removed. If the umask value is set improperly, the permission of new files may be too...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the KVM x86 mmu not treating NX as an NPT valid bit, which could result in a reserved bit set warning...

It is an offensive tool for Linux. This is a tutorial for Linux exploit development, specifically targeting stack and heap security mechanisms. The tutorial covers various topics, including format string attacks, integer overflow, and buffer overflow attacks. It also discusses how to bypass...

Privilege Escalation

kernel is vulnerable to privilege escalation. The vulnerability exists as the NFSv4 client was missing a file permission check for the execute bit in some situations. This could allow local, unprivileged users to run non-executable files on NFSv4 mounted file systems...

IBM Domino 8.5.x < 8.5.3 Fix Pack 6 Interim Fix 2 NX Memory Protection Disabled

According to its banner, the version of IBM Domino formerly IBM Lotus Domino on the remote host is 8.5.x prior to 8.5.3 Fix Pack 6 FP6 Interim Fix 2 IF2. It is, therefore, more susceptible to exploitation due to the GCC '-z execstack' flag being used during compilation. This flag disables the...
