Ubuntu Security Notice 6626-1 - Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel when handling sessions operations. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code. Marek Marczykowski-Górecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a denial of service.

It was discovered that the SMB network file sharing protocol implementation in the Linux kernel did not properly handle certain error conditions, leading to a use-after-free vulnerability. Lin Ma discovered that the netfilter subsystem in the Linux kernel did not properly validate network family support while creating a new netfilter table. Various other issues were discovered and addressed.

Ubuntu Security Notice 6625-1 - Marek Marczykowski-Górecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a denial of service. Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver in the Linux kernel during device removal. A privileged attacker could use this to cause a denial of service.

PHPMailer before 1.7.4, when configured to use sendmail, allows remote attackers to execute arbitrary shell commands via shell metacharacters in the SendmailSend function in `class.phpmailer.php`. ### Impact Shell command injection, remotely exploitable if host application does not filter user data appropriately. ### Patches Fixed in 1.7.4 ### Workarounds Filter and validate user-supplied data before putting in the into the `Sender` property. ### References https://nvd.nist.gov/vuln/detail/CVE-2007-3215 ### For more information If you have any questions or comments about this advisory: * Open a private issue in [the PHPMailer project](https://github.com/PHPMailer/PHPMailer)

By Waqas The new variant of Mispadu Stealer was discovered by Palo Alto's Unit 42 researchers while investigating the Windows Defender SmartScreen vulnerability. This is a post from HackRead.com Read the original post: Mispadu Stealer’s New Variant Targets Browser Data of Mexican Users

Ubuntu Security Notice 6621-1 - It was discovered that ImageMagick incorrectly handled certain values when processing BMP files. An attacker could exploit this to cause a denial of service.

The SEC isn’t giving SaaS a free pass. Applicable public companies, known as “registrants,” are now subject to cyber incident disclosure and cybersecurity readiness requirements for data stored in SaaS systems, along with the 3rd and 4th party apps connected to them.  The new cybersecurity mandates make no distinction between data exposed in a breach that was stored on-premise, in the

MiniZinc version 2.7.6 suffers from a null pointer vulnerability.

Ubuntu Security Notice 6609-1 - Lin Ma discovered that the netfilter subsystem in the Linux kernel did not properly validate network family support while creating a new netfilter table. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could cause a denial of service or possibly expose sensitive information.
