ELF header parsing library doesn't check for valid offset

The crate has several unsafe sections that don't perform proper pointer validation. An example can be found in the following function: fn sectionheaderraw&self - &ET::SectionHeader let shoff = self.elfheader.sectionheaderoffset as usize; let shnum = self.elfheader.sectionheaderentrynum as usize;...

New Backdoor Created Using Leaked CIA's Hive Malware Discovered in the Wild

Unidentified threat actors have deployed a new backdoor that borrows its features from the U.S. Central Intelligence Agency CIA's Hive multi-platform malware suite, the source code of which was released by WikiLeaks in November 2017. "This is the first time we caught a variant of the CIA Hive...

OESA-2023-1001 patchelf security update

PatchELF is a simple utility for modifying an existing ELF executable or library. It can change the dynamic loader "ELF interpreter" of an executable and change the RPATH of an executable or library. Security Fixes: Patchelf v0.9 was discovered to contain an out-of-bounds read via the function...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the Linux kernel related to the handling of the ELF header buffer during kexec. Specifically, a superfluous vfree call within the crash load segments function's error pa...

PatchELF buffer error vulnerability

PatchELF is a simple utility program for modifying existing ELF executables and libraries in the Nix/Nixpkgs/NixOS open source. A security vulnerability exists in PatchELF version v0.9, which stems from the discovery that Patchelf contains out-of-bounds reads via the function modifyRPath in...

CVE-2022-23523

In versions prior to 0.8.1, the linux-loader crate uses the offsets and sizes provided in the ELF headers to determine the offsets to read from. If those offsets point beyond the end of the file this could lead to Virtual Machine Monitors using the linux-loader crate entering an infinite loop if...
