Ubuntu Security Notice USN-5841-1
Posted Feb 3, 2023
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5841-1 - It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges. This issue was only fixed in Ubuntu 14.04 ESM. It was discovered that LibTIFF was incorrectly accessing a data structure when processing data with the tiffcrop tool, which could lead to a heap buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code.

OpenSSH 9.2p1
Posted Feb 2, 2023
Authored by Damien Miller | Site openssh.com

This is a Linux/portable port of OpenBSD's excellent OpenSSH. OpenSSH is based on the last free version of Tatu Ylonen's SSH with all patent-encumbered algorithms removed, all known security bugs fixed, new features reintroduced, and many other clean-ups.

Changes: This release contains fixes for two security problems and a memory safety problem. The memory safety problem is not believed to be exploitable, but they report most network-reachable memory faults as security bugs.

io_uring Same Type Object Reuse Privilege Escalation
Posted Feb 1, 2023
Authored by h00die, Mathias Krause, Ryota Shiga | Site metasploit.com

This Metasploit module exploits a bug in io_uring leading to an additional put_cred() that can be exploited to hijack credentials of other processes. This exploit will spawn SUID programs to get the freed cred object reallocated by a privileged process and abuse them to create a SUID root binary that will pop a shell. The dangling cred pointer will, however, lead to a kernel panic as soon as the task terminates and its credentials are destroyed. We therefore detach from the controlling terminal, block all signals and rest in silence until the system shuts down and we get killed hard, just to cry in vain, seeing the kernel collapse. The bug affected kernels from v5.12-rc3 to v5.14-rc7. More than 1 CPU is required for exploitation. Successfully tested against Ubuntu 22.04.01 with kernel 5.13.12-051312-generic.

vmwgfx Driver File Descriptor Handling Privilege Escalation
Posted Feb 1, 2023
Authored by h00die, Mathias Krause | Site metasploit.com

If the vmwgfx driver fails to copy the fence_rep object to userland, it tries to recover by deallocating the (already populated) file descriptor. This is wrong, as the fd gets released via put_unused_fd() which shouldn't be used, as the fd table slot was already populated via the previous call to fd_install(). This leaves userland with a valid fd table entry pointing to a freed file object. The authors use this bug to overwrite a SUID binary with their payload and gain root. Linux kernel versions 4.14-rc1 - 5.17-rc1 are vulnerable. Successfully tested against Ubuntu 22.04.01 with kernel 5.13.12-051312-generic.
