OpenSLP as used in VMware ESXi (7.0 before ESXi_7.0.1-0.0.16850804, 6.7 before ESXi670-202010401-SG, 6.5 before ESXi650-202010401-SG) has a use-after-free issue. A malicious actor residing in the management network who has access to port 427 on an ESXi machine may be able to trigger a use-after-free in the OpenSLP service resulting in remote code execution.

An out-of-bounds read was addressed with improved input validation. This issue is fixed in macOS Catalina 10.15.6, tvOS 13.4.8, watchOS 6.2.8. A remote attacker may be able to cause unexpected system termination or corrupt kernel memory.

This issue was addressed by encrypting communications over the network to devices running iOS 14, iPadOS 14, tvOS 14, and watchOS 7. This issue is fixed in iOS 14.0 and iPadOS 14.0, Xcode 12.0. An attacker in a privileged network position may be able to execute arbitrary code on a paired device during a debug session over the network.

An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in Safari 14.0. Processing maliciously crafted web content may lead to code execution.

An exploitable code execution vulnerability exists in the fsck_chk_orphan_node functionality of F2fs-Tools F2fs.Fsck 1.13. A specially crafted f2fs filesystem can cause a heap buffer overflow resulting in a code execution. An attacker can provide a malicious file to trigger this vulnerability.

An exploitable information disclosure vulnerability exists in the init_node_manager functionality of F2fs-Tools F2fs.Fsck 1.12 and 1.13. A specially crafted filesystem can be used to disclose information. An attacker can provide a malicious file to trigger this vulnerability.

An exploitable information disclosure vulnerability exists in the get_dnode_of_data functionality of F2fs-Tools F2fs.Fsck 1.13. A specially crafted f2fs filesystem can cause information disclosure resulting in a information disclosure. An attacker can provide a malicious file to trigger this vulnerability.

An exploitable code execution vulnerability exists in the multiple devices functionality of F2fs-Tools F2fs.Fsck 1.13. A specially crafted f2fs filesystem can cause Information overwrite resulting in a code execution. An attacker can provide a malicious file to trigger this vulnerability.

An exploitable information disclosure vulnerability exists in the dev_read functionality of F2fs-Tools F2fs.Fsck 1.13. A specially crafted f2fs filesystem can cause an uninitialized read resulting in an information disclosure. An attacker can provide a malicious file to trigger this vulnerability.

Sympa through 6.2.57b.2 allows a local privilege escalation from the sympa user account to full root access by modifying the sympa.conf configuration file (which is owned by sympa) and parsing it through the setuid sympa_newaliases-wrapper executable.
