Security Vulnerabilities
- CVEs Published In April 2024
In PHP 8.3.* before 8.3.5, function mb_encode_mimeheader() runs endlessly for some inputs that contain long strings of non-space characters followed by a space. This could lead to a potential DoS attack if a hostile user sends data to an application that uses this function.
In PHP version 8.1.* before 8.1.28, 8.2.* before 8.2.18, 8.3.* before 8.3.5, if a password stored with password_hash() starts with a null byte (\x00), testing a blank string as the password via password_verify() will incorrectly return true.
The system configuration interface of HGiga iSherlock (including MailSherlock, SpamSherock, AuditSherlock) fails to filter special characters in certain function parameters, allowing remote attackers with administrative privileges to exploit this vulnerability for Command Injection attacks, enabling execution of arbitrary system commands.
In PHP versions 8.1.* before 8.1.28, 8.2.* before 8.2.18, 8.3.* before 8.3.5, when using proc_open() command with array syntax, due to insufficient escaping, if the arguments of the executed command are controlled by a malicious user, the user can supply arguments that would execute arbitrary commands in Windows shell.
The system configuration interface of HGiga iSherlock (including MailSherlock, SpamSherlock, AuditSherlock) fails to filter special characters in certain function parameters, allowing remote attackers with administrative privileges to exploit this vulnerability to download arbitrary system files.
The email search interface of HGiga iSherlock (including MailSherlock, SpamSherock, AuditSherlock) fails to filter special characters in certain function parameters, allowing remote attackers with administrative privileges to exploit this vulnerability for Command Injection attacks, enabling execution of arbitrary system commands.
The account management interface of HGiga iSherlock (including MailSherlock, SpamSherlock, AuditSherlock) fails to filter special characters in certain function parameters, allowing remote attackers with administrative privileges to exploit this vulnerability to download arbitrary system files.
RARLAB WinRAR before 7.00, on Linux and UNIX platforms, allows attackers to spoof the screen output, or cause a denial of service, via ANSI escape sequences.
Delinea Secret Server before 11.7.000001 allows attackers to bypass authentication via the SOAP API in SecretServer/webservices/SSWebService.asmx. This is related to a hardcoded key, the use of the integer 2 for the Admin user, and removal of the oauthExpirationId attribute.
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix hang during unmount when stopping a space reclaim worker
Often when running generic/562 from fstests we can hang during unmount,
resulting in a trace like this:

What happens is the following:
1) The cleaner kthread tries to start a transaction to delete an unused
block group, but the metadata reservation can not be satisfied right
away, so a reservation ticket is created and it starts the async
metadata reclaim task (fs_info->async_reclaim_work);
2) Writeback for all the filler inodes with an i_size of 2K starts
(generic/562 creates a lot of 2K files with the goal of filling
metadata space). We try to create an inline extent for them, but we
fail when trying to insert the inline extent with -ENOSPC (at
cow_file_range_inline()) - since this is not critical, we fallback
to non-inline mode (back to cow_file_range()), reserve extents
