CVE’s

An issue was discovered in Suricata 4.1.3. The code mishandles the case of sending a network packet with the right type, such that the function DecodeEthernet in decode-ethernet.c is executed a second time. At this point, the algorithm cuts the first part of the packet and doesn't determine the current length. Specifically, if the packet is exactly 28 long, in the first iteration it subtracts 14 bytes. Then, it is working with a packet length of 14. At this point, the case distinction says it is a valid packet. After that it casts the packet, but this packet has no type, and the program crashes at the type case distinction.

An issue was discovered in Suricata 4.1.3. The function ftp_pasv_response lacks a check for the length of part1 and part2, leading to a crash within the ftp/mod.rs file.

An issue was discovered in Suricata 4.1.3. The function process_reply_record_v3 lacks a check for the length of reply.data. It causes an invalid memory access and the program crashes within the nfs/nfs3.rs file.

An issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the function SSHParseBanner is composed only of a n character, then the program runs into a heap-based buffer over-read. This occurs because the erroneous search for r results in an integer underflow.

An issue was discovered in Suricata 4.1.3. If the network packet does not have the right length, the parser tries to access a part of a DHCP packet. At this point, the Rust environment runs into a panic in parse_clientid_option in the dhcp/parser.rs file.

An issue was discovered in Suricata 4.1.3. If the function filetracker_newchunk encounters an unsafe "Some(sfcm) => { ft.new_chunk }" item, then the program enters an smb/files.rs error condition and crashes.

A buffer over-read issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the decode-mpls.c function DecodeMPLS is composed only of a packet of source address and destination address plus the correct type field and the right number for shim, an attacker can manipulate the control flow, such that the condition to leave the loop is true. After leaving the loop, the network packet has a length of 2 bytes. There is no validation of this length. Later on, the code tries to read at an empty position, leading to a crash.

A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers, aka 'Scripting Engine Memory Corruption Vulnerability'. This CVE ID is unique from CVE-2019-0920, CVE-2019-0988, CVE-2019-1055, CVE-2019-1080.

It is possible for an attacker with regular user access to the web application of Pydio through 8.2.2 to trick an administrator user into opening a link shared through the application, that in turn opens a shared file that contains JavaScript code (that is executed in the context of the victim user to obtain sensitive information such as session identifiers and perform actions on behalf of him/her).

The ImageMagick plugin that is installed by default in Pydio through 8.2.2 does not perform the appropriate validation and sanitization of user supplied input in the plugin's configuration options, allowing arbitrary shell commands to be entered that result in command execution on the underlying operating system, with the privileges of the local user running the web server. The attacker must be authenticated into the application with an administrator user account in order to be able to edit the affected plugin configuration.
