Security Vulnerabilities - CVEs Published In February 2024
MantisBT is an open source issue tracker. Prior to version 2.26.1, an unauthenticated attacker who knows a user's email address and username can hijack the user's account by poisoning the link in the password reset notification message. A patch is available in version 2.26.1. As a workaround, define `$g_path` as appropriate in `config_inc.php`.

kedi ElectronCord is a bot management tool for Discord. Commit aaaeaf4e6c99893827b2eea4dd02f755e1e24041 exposes an account access token in the `config.json` file. Malicious actors could potentially exploit this vulnerability to gain unauthorized access to sensitive information or perform malicious actions on behalf of the repository owner. As of time of publication, it is unknown whether the owner of the repository has rotated the token or taken other mitigation steps aside from informing users of the situation.

In the Linux kernel, the following vulnerability has been resolved:
f2fs: explicitly null-terminate the xattr list
When setting an xattr, explicitly null-terminate the xattr list. This
eliminates the fragile assumption that the unused xattr space is always
zeroed.

In the Linux kernel, the following vulnerability has been resolved:
binder: fix use-after-free in shinker's callback
The mmap read lock is used during the shrinker's callback, which means
that using alloc->vma pointer isn't safe as it can race with munmap().
As of commit dd2283f2605e ("mm: mmap: zap pages with read mmap_sem in
munmap") the mmap lock is downgraded after the vma has been isolated.
I was able to reproduce this issue by manually adding some delays and
triggering page reclaiming through the shrinker's debug sysfs. The
following KASAN report confirms the UAF:
==================================================================

Fix this issue by performing instead a vma_lookup() which will fail to
find the vma that was isolated before the mmap lock downgrade. Note that
this option has better performance than upgrading to a mmap write lock
which would increase contention. Plus, mmap_write_trylock() has been
recently removed anyway.

In the Linux kernel, the following vulnerability has been resolved:
uio: Fix use-after-free in uio_open
core-1 core-2
-------------------------------------------------------
uio_unregister_device uio_open
idev = idr_find()
device_unregister(&idev->dev)
put_device(&idev->dev)
uio_device_release
get_device(&idev->dev)
kfree(idev)
uio_free_minor(minor)
uio_release
put_device(&idev->dev)
kfree(idev)
-------------------------------------------------------
In the core-1 uio_unregister_device(), the device_unregister will kfree
idev when the idev->dev kobject ref is 1. But after core-1
device_unregister, put_device and before doing kfree, the core-2 may
get_device. Then:
1. After core-1 kfree idev, the core-2 will do use-after-free for idev.
2. When core-2 do uio_release and put_device, the idev will be double
freed.
To address this issue, we can get idev atomic & inc idev reference with
minor_lock.

When ssl was enabled for Mongo Hook, default settings included "allow_insecure" which caused that certificates were not validated. This was unexpected and undocumented.
Users are recommended to upgrade to version 4.0.0, which fixes this issue.
