CVE-2020-29479 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-11-21 7.2 HIGH 8.8 HIGH
An issue was discovered in Xen through 4.14.x. In the Ocaml xenstored implementation, the internal representation of the tree has special cases for the root node, because this node has no parent. Unfortunately, permissions were not checked for certain operations on the root node. Unprivileged guests can get and modify permissions, list, and delete the root node. (Deleting the whole xenstore tree is a host-wide denial of service.) Achieving xenstore write access is also possible. All systems using oxenstored are vulnerable. Building and using oxenstored is the default in the upstream Xen distribution, if the Ocaml compiler is available. Systems using C xenstored are not vulnerable.
CVE-2020-29385 3 Canonical, Fedoraproject, Gnome 3 Ubuntu Linux, Fedora, Gdk-pixbuf 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
GNOME gdk-pixbuf (aka GdkPixbuf) before 2.42.2 allows a denial of service (infinite loop) in lzw.c in the function write_indexes. if c->self_code equals 10, self->code_table[10].extends will assign the value 11 to c. The next execution in the loop will assign self->code_table[11].extends to c, which will give the value of 10. This will make the loop run infinitely. This bug can, for example, be triggered by calling this function with a GIF image with LZW compression that is crafted in a special way.
CVE-2020-29130 3 Debian, Fedoraproject, Libslirp Project 3 Debian Linux, Fedora, Libslirp 2024-11-21 4.0 MEDIUM 4.3 MEDIUM
slirp.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.
CVE-2020-29129 3 Debian, Fedoraproject, Libslirp Project 3 Debian Linux, Fedora, Libslirp 2024-11-21 4.0 MEDIUM 4.3 MEDIUM
ncsi.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.
CVE-2020-29074 3 Debian, Fedoraproject, X11vnc Project 3 Debian Linux, Fedora, X11vnc 2024-11-21 6.5 MEDIUM 8.8 HIGH
scan.c in x11vnc 0.9.16 uses IPC_CREAT|0777 in shmget calls, which allows access by actors other than the current user.
CVE-2020-28972 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
In SaltStack Salt before 3002.5, authentication to VMware vcenter, vsphere, and esxi servers (in the vmware.py files) does not always validate the SSL/TLS certificate.
CVE-2020-28949 4 Debian, Drupal, Fedoraproject and 1 more 4 Debian Linux, Drupal, Fedora and 1 more 2024-11-21 6.8 MEDIUM 7.8 HIGH
Archive_Tar through 1.4.10 has :// filename sanitization only to address phar attacks, and thus any other stream-wrapper attack (such as file:// to overwrite files) can still succeed.
CVE-2020-28948 4 Debian, Drupal, Fedoraproject and 1 more 4 Debian Linux, Drupal, Fedora and 1 more 2024-11-21 6.8 MEDIUM 7.8 HIGH
Archive_Tar through 1.4.10 allows an unserialization attack because phar: is blocked but PHAR: is not blocked.
CVE-2020-28941 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in drivers/accessibility/speakup/spk_ttyio.c in the Linux kernel through 5.9.9. Local attackers on systems with the speakup driver could cause a local denial of service attack, aka CID-d41227544427. This occurs because of an invalid free when the line discipline is used more than once.
CVE-2020-28928 4 Debian, Fedoraproject, Musl-libc and 1 more 4 Debian Linux, Fedora, Musl and 1 more 2024-11-21 2.1 LOW 5.5 MEDIUM
In musl libc through 1.2.1, wcsnrtombs mishandles particular combinations of destination buffer size and source character limit, as demonstrated by an invalid write access (buffer overflow).
CVE-2020-28924 2 Fedoraproject, Rclone 2 Fedora, Rclone 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Rclone before 1.53.3. Due to the use of a weak random number generator, the password generator has been producing weak passwords with much less entropy than advertised. The suggested passwords depend deterministically on the time the second rclone was started. This limits the entropy of the passwords enormously. These passwords are often used in the crypt backend for encryption of data. It would be possible to make a dictionary of all possible passwords with about 38 million entries per password length. This would make decryption of secret material possible with a plausible amount of effort. NOTE: all passwords generated by affected versions should be changed.
CVE-2020-28636 3 Cgal, Debian, Fedoraproject 3 Computational Geometry Algorithms Library, Debian Linux, Fedora 2024-11-21 7.5 HIGH 9.8 CRITICAL
A code execution vulnerability exists in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. An oob read vulnerability exists in Nef_S2/SNC_io_parser.h SNC_io_parser::read_sloop() slh->twin() An attacker can provide malicious input to trigger this vulnerability.
CVE-2020-28601 3 Cgal, Debian, Fedoraproject 3 Computational Geometry Algorithms Library, Debian Linux, Fedora 2024-11-21 7.5 HIGH 9.8 CRITICAL
A code execution vulnerability exists in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. An oob read vulnerability exists in Nef_2/PM_io_parser.h PM_io_parser::read_vertex() Face_of[] OOB read. An attacker can provide malicious input to trigger this vulnerability.
CVE-2020-28599 2 Fedoraproject, Openscad 2 Fedora, Openscad 2024-11-21 6.8 MEDIUM 7.8 HIGH
A stack-based buffer overflow vulnerability exists in the import_stl.cc:import_stl() functionality of Openscad openscad-2020.12-RC2. A specially crafted STL file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2020-28591 2 Fedoraproject, Slic3r 2 Fedora, Libslic3r 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
An out-of-bounds read vulnerability exists in the AMF File AMFParserContext::endElement() functionality of Slic3r libslic3r 1.3.0 and Master Commit 92abbc42. A specially crafted AMF file can lead to information disclosure. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2020-28493 2 Fedoraproject, Palletsprojects 2 Fedora, Jinja 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDoS vulnerability is mainly due to the `_punctuation_re regex` operator and its use of multiple wildcards. The last wildcard is the most exploitable as it searches for trailing punctuation. This issue can be mitigated by Markdown to format user content instead of the urlize filter, or by implementing request timeouts and limiting process memory.
CVE-2020-28463 2 Fedoraproject, Reportlab 2 Fedora, Reportlab 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
All versions of package reportlab are vulnerable to Server-side Request Forgery (SSRF) via img tags. In order to reduce risk, use trustedSchemes & trustedHosts (see in Reportlab's documentation) Steps to reproduce by Karan Bamal: 1. Download and install the latest package of reportlab 2. Go to demos -> odyssey -> dodyssey 3. In the text file odyssey.txt that needs to be converted to pdf inject <img src="http://127.0.0.1:5000" valign="top"/> 4. Create a nc listener nc -lp 5000 5. Run python3 dodyssey.py 6. You will get a hit on your nc showing we have successfully proceded to send a server side request 7. dodyssey.py will show error since there is no img file on the url, but we are able to do SSRF
CVE-2020-28374 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 5.5 MEDIUM 8.1 HIGH
In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are proxied via an attacker-selected backstore.
CVE-2020-28368 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-11-21 2.1 LOW 4.4 MEDIUM
Xen through 4.14.x allows guest OS administrators to obtain sensitive information (such as AES keys from outside the guest) via a side-channel attack on a power/energy monitoring interface, aka a "Platypus" attack. NOTE: there is only one logically independent fix: to change the access control for each such interface in Xen.
CVE-2020-28366 3 Fedoraproject, Golang, Netapp 4 Fedora, Go, Cloud Insights Telegraf Agent and 1 more 2024-11-21 5.1 MEDIUM 7.5 HIGH
Code injection in the go command with cgo before Go 1.14.12 and Go 1.15.5 allows arbitrary code execution at build time via a malicious unquoted symbol name in a linked object file.
