CVE-2020-29483 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2023-11-07 4.9 MEDIUM 6.5 MEDIUM
An issue was discovered in Xen through 4.14.x. Xenstored and guests communicate via a shared memory page using a specific protocol. When a guest violates this protocol, xenstored will drop the connection to that guest. Unfortunately, this is done by just removing the guest from xenstored's internal management, resulting in the same actions as if the guest had been destroyed, including sending an @releaseDomain event. @releaseDomain events do not say that the guest has been removed. All watchers of this event must look at the states of all guests to find the guest that has been removed. When an @releaseDomain is generated due to a domain xenstored protocol violation, because the guest is still running, the watchers will not react. Later, when the guest is actually destroyed, xenstored will no longer have it stored in its internal data base, so no further @releaseDomain event will be sent. This can lead to a zombie domain; memory mappings of that guest's memory will not be removed, due to the missing event. This zombie domain will be cleaned up only after another domain is destroyed, as that will trigger another @releaseDomain event. If the device model of the guest that violated the Xenstore protocol is running in a stub-domain, a use-after-free case could happen in xenstored, after having removed the guest from its internal data base, possibly resulting in a crash of xenstored. A malicious guest can block resources of the host for a period after its own death. Guests with a stub domain device model can eventually crash xenstored, resulting in a more serious denial of service (the prevention of any further domain management operations). Only the C variant of Xenstore is affected; the Ocaml variant is not affected. Only HVM guests with a stubdom device model can cause a serious DoS.
CVE-2020-28951 1 Openwrt 1 Openwrt 2023-11-07 10.0 HIGH 9.8 CRITICAL
libuci in OpenWrt before 18.06.9 and 19.x before 19.07.5 may encounter a use after free when using malicious package names. This is related to uci_parse_package in file.c and uci_strdup in util.c.
CVE-2020-27918 4 Apple, Debian, Fedoraproject and 1 more 11 Icloud, Ipados, Iphone Os and 8 more 2023-11-07 6.8 MEDIUM 7.8 HIGH
A use after free issue was addressed with improved memory management. This issue is fixed in macOS Big Sur 11.0.1, watchOS 7.1, iOS 14.2 and iPadOS 14.2, iCloud for Windows 11.5, Safari 14.0.1, tvOS 14.2, iTunes 12.11 for Windows. Processing maliciously crafted web content may lead to arbitrary code execution.
CVE-2020-27675 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2023-11-07 4.7 MEDIUM 4.7 MEDIUM
An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash via events for an in-reconfiguration paravirtualized device, aka CID-073d0552ead5.
CVE-2020-27672 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2023-11-07 6.9 MEDIUM 7.0 HIGH
An issue was discovered in Xen through 4.14.x allowing x86 guest OS users to cause a host OS denial of service, achieve data corruption, or possibly gain privileges by exploiting a race condition that leads to a use-after-free involving 2MiB and 1GiB superpages.
CVE-2020-25669 3 Debian, Linux, Netapp 21 Debian Linux, Linux Kernel, Cloud Backup and 18 more 2023-11-07 7.2 HIGH 7.8 HIGH
A vulnerability was found in the Linux Kernel where the function sunkbd_reinit having been scheduled by sunkbd_interrupt before sunkbd being freed. Though the dangling pointer is set to NULL in sunkbd_disconnect, there is still an alias in sunkbd_reinit causing Use After Free.
CVE-2020-25632 4 Fedoraproject, Gnu, Netapp and 1 more 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more 2023-11-07 7.2 HIGH 8.2 HIGH
A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-23856 2 Fedoraproject, Gnu 2 Fedora, Cflow 2023-11-07 2.1 LOW 5.5 MEDIUM
Use-after-Free vulnerability in cflow 1.6 in the void call(char *name, int line) function at src/parser.c, which could cause a denial of service via the pointer variable caller->callee.
CVE-2020-21722 1 Ogg Video Tools Project 1 Ogg Video Tools 2023-11-07 N/A 7.8 HIGH
Buffer Overflow vulnerability in oggvideotools 0.9.1 allows remote attackers to run arbitrary code via opening of crafted ogg file.
CVE-2020-1983 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 2.1 LOW 6.5 MEDIUM
A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service.
CVE-2020-1752 4 Canonical, Debian, Gnu and 1 more 9 Ubuntu Linux, Debian Linux, Glibc and 6 more 2023-11-07 3.7 LOW 7.0 HIGH
A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32.
CVE-2020-1712 3 Debian, Redhat, Systemd Project 7 Debian Linux, Ceph Storage, Discovery and 4 more 2023-11-07 4.6 MEDIUM 7.8 HIGH
A heap use-after-free vulnerability was found in systemd before version v245-rc1, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafted dbus messages.
CVE-2020-16600 1 Artifex 1 Mupdf 2023-11-07 6.8 MEDIUM 7.8 HIGH
A Use After Free vulnerability exists in Artifex Software, Inc. MuPDF library 1.17.0-rc1 and earlier when a valid page was followed by a page with invalid pixmap dimensions, causing bander - a static - to point to previously freed memory instead of a newband_writer.
CVE-2020-16592 3 Fedoraproject, Gnu, Netapp 3 Fedora, Binutils, Ontap Select Deploy Administration Utility 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
A use after free issue exists in the Binary File Descriptor (BFD) library (aka libbfd) in GNU Binutils 2.34 in bfd_hash_lookup, as demonstrated in nm-new, that can cause a denial of service via a crafted file.
