| CVE-2020-16092 | 5 Canonical, Debian, Opensuse and 2 more | 8 Ubuntu Linux, Debian Linux, Leap and 5 more | 2024-08-04 | 3.8 Low |
| In QEMU through 5.0.0, an assertion failure can occur in the network packet processing. This issue affects the e1000e and vmxnet3 network devices. A malicious guest user/process could use this flaw to abort the QEMU process on the host, resulting in a denial of service condition in net_tx_pkt_add_raw_fragment in hw/net/net_tx_pkt.c. | ||||
| CVE-2020-15900 | 3 Artifex, Canonical, Opensuse | 3 Ghostscript, Ubuntu Linux, Leap | 2024-08-04 | 9.8 Critical |
| A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator can allow overriding of file access controls. The 'rsearch' calculation for the 'post' size resulted in a size that was too large, and could underflow to max uint32_t. This was fixed in commit 5d499272b95a6b890a1397e11d20937de000d31b. | ||||
| CVE-2020-15890 | 4 Canonical, Debian, Luajit and 1 more | 4 Ubuntu Linux, Debian Linux, Luajit and 1 more | 2024-08-04 | 7.5 High |

| CVE-2020-15863 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2024-08-04 | 5.3 Medium |
| hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555. | ||||
| CVE-2020-15862 | 4 Canonical, Net-snmp, Netapp and 1 more | 11 Ubuntu Linux, Net-snmp, Cloud Backup and 8 more | 2024-08-04 | 7.8 High |
| Net-SNMP through 5.8 has Improper Privilege Management because SNMP WRITE access to the EXTEND MIB provides the ability to run arbitrary commands as root. | ||||
| CVE-2020-15861 | 3 Canonical, Net-snmp, Netapp | 5 Ubuntu Linux, Net-snmp, Cloud Backup and 2 more | 2024-08-04 | 7.8 High |
| Net-SNMP through 5.7.3 allows Escalation of Privileges because of UNIX symbolic link (symlink) following. | ||||
| CVE-2020-15811 | 6 Canonical, Debian, Fedoraproject and 3 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-08-04 | 6.5 Medium |
| An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Splitting attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the browser cache and any downstream caches with content from an arbitrary source. Squid uses a string search instead of parsing the Transfer-Encoding header to find chunked encoding. This allows an attacker to hide a second request inside Transfer-Encoding: it is interpreted by Squid as chunked and split out into a second request delivered upstream. Squid will then deliver two distinct responses to the client, corrupting any downstream caches. | ||||
| CVE-2020-15810 | 6 Canonical, Debian, Fedoraproject and 3 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-08-04 | 6.5 Medium |
| An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches with content from an arbitrary source. When configured for relaxed header parsing (the default), Squid relays headers containing whitespace characters to upstream servers. When this occurs as a prefix to a Content-Length header, the frame length specified will be ignored by Squid (allowing for a conflicting length to be used from another Content-Length header) but relayed upstream. | ||||
| CVE-2020-15655 | 3 Canonical, Mozilla, Opensuse | 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more | 2024-08-04 | 6.5 Medium |
| A redirected HTTP request which is observed or modified through a web extension could bypass existing CORS checks, leading to potential disclosure of cross-origin information. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. | ||||
| CVE-2020-15780 | 4 Canonical, Linux, Opensuse and 1 more | 6 Ubuntu Linux, Linux Kernel, Leap and 3 more | 2024-08-04 | 6.7 Medium |
| An issue was discovered in drivers/acpi/acpi_configfs.c in the Linux kernel before 5.7.7. Injection of malicious ACPI tables via configfs could be used by attackers to bypass lockdown and secure boot restrictions, aka CID-75b0cea7bf30. | ||||
| CVE-2020-15659 | 4 Canonical, Mozilla, Opensuse and 1 more | 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more | 2024-08-04 | 8.8 High |
| Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR 78.0.
