CVE-2022-33747 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2022-12-09 N/A 3.8 LOW
Arm: unbounded memory consumption for 2nd-level page tables Certain actions require e.g. removing pages from a guest's P2M (Physical-to-Machine) mapping. When large pages are in use to map guest pages in the 2nd-stage page tables, such a removal operation may incur a memory allocation (to replace a large mapping with individual smaller ones). These memory allocations are taken from the global memory pool. A malicious guest might be able to cause the global memory pool to be exhausted by manipulating its own P2M mappings.
CVE-2022-42324 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2022-12-09 N/A 5.5 MEDIUM
Oxenstored 32->31 bit integer truncation issues Integers in Ocaml are 63 or 31 bits of signed precision. The Ocaml Xenbus library takes a C uint32_t out of the ring and casts it directly to an Ocaml integer. In 64-bit Ocaml builds this is fine, but in 32-bit builds, it truncates off the most significant bit, and then creates unsigned/signed confusion in the remainder. This in turn can feed a negative value into logic not expecting a negative value, resulting in unexpected exceptions being thrown. The unexpected exception is not handled suitably, creating a busy-loop trying (and failing) to take the bad packet out of the xenstore ring.
CVE-2020-36430 2 Fedoraproject, Libass Project 2 Fedora, Libass 2022-12-09 6.8 MEDIUM 7.8 HIGH
libass 0.15.x before 0.15.1 has a heap-based buffer overflow in decode_chars (called from decode_font and process_text) because the wrong integer data type is used for subtraction.
CVE-2021-30547 4 Debian, Fedoraproject, Google and 1 more 4 Debian Linux, Fedora, Chrome and 1 more 2022-12-09 6.8 MEDIUM 8.8 HIGH
Out of bounds write in ANGLE in Google Chrome prior to 91.0.4472.101 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page.
CVE-2021-31924 2 Fedoraproject, Yubico 2 Fedora, Pam-u2f 2022-12-09 4.6 MEDIUM 6.8 MEDIUM
Yubico pam-u2f before 1.1.1 has a logic issue that, depending on the pam-u2f configuration and the application used, could lead to a local PIN bypass. This issue does not allow user presence (touch) or cryptographic signature verification to be bypassed, so an attacker would still need to physically possess and interact with the YubiKey or another enrolled authenticator. If pam-u2f is configured to require PIN authentication, and the application using pam-u2f allows the user to submit NULL as the PIN, pam-u2f will attempt to perform a FIDO2 authentication without PIN. If this authentication is successful, the PIN requirement is bypassed.
CVE-2021-28957 5 Debian, Fedoraproject, Lxml and 2 more 5 Debian Linux, Fedora, Lxml and 2 more 2022-12-09 4.3 MEDIUM 6.1 MEDIUM
An XSS vulnerability was discovered in python-lxml's clean module versions before 4.6.3. When disabling the safe_attrs_only and forms arguments, the Cleaner class does not remove the formaction attribute allowing for JS to bypass the sanitizer. A remote attacker could exploit this flaw to run arbitrary JS code on users who interact with incorrectly sanitized HTML. This issue is patched in lxml 4.6.3.
CVE-2022-42314 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2022-12-09 N/A 6.5 MEDIUM
Xenstore: guests can let run xenstored out of memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction
CVE-2022-21698 3 Fedoraproject, Prometheus, Rdo Project 4 Extra Packages For Enterprise Linux, Fedora, Client Golang and 1 more 2022-12-09 5.0 MEDIUM 7.5 HIGH
client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version 1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`; not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`. client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow a limited set of methods.
CVE-2021-28861 2 Fedoraproject, Python 2 Fedora, Python 2022-12-09 N/A 7.4 HIGH
** DISPUTED ** Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is disputed by a third party because the http.server.html documentation page states "Warning: http.server is not recommended for production. It only implements basic security checks."
CVE-2021-43818 5 Debian, Fedoraproject, Lxml and 2 more 12 Debian Linux, Fedora, Lxml and 9 more 2022-12-09 6.8 MEDIUM 7.1 HIGH
lxml is a library for processing XML and HTML in the Python language. Prior to version 4.6.5, the HTML Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG files embedded using data URIs. Users that employ the HTML cleaner in a security relevant context should upgrade to lxml 4.6.5 to receive a patch. There are no known workarounds available.
CVE-2021-41556 2 Fedoraproject, Squirrel-lang 2 Fedora, Squirrel 2022-12-09 N/A 10.0 CRITICAL
sqclass.cpp in Squirrel through 2.2.5 and 3.x through 3.1 allows an out-of-bounds read (in the core interpreter) that can lead to Code Execution. If a victim executes an attacker-controlled squirrel script, it is possible for the attacker to break out of the squirrel script sandbox even if all dangerous functionality such as File System functions has been disabled. An attacker might abuse this bug to target (for example) Cloud services that allow customization via SquirrelScripts, or distribute malware through video games that embed a Squirrel Engine.
CVE-2022-30292 2 Fedoraproject, Squirrel-lang 2 Fedora, Squirrel 2022-12-09 7.5 HIGH 10.0 CRITICAL
Heap-based buffer overflow in sqbaselib.cpp in SQUIRREL 3.2 due to lack of a certain sq_reservestack call.
CVE-2022-25763 3 Apache, Debian, Fedoraproject 3 Traffic Server, Debian Linux, Fedora 2022-12-09 N/A 7.5 HIGH
Improper Input Validation vulnerability in HTTP/2 request validation of Apache Traffic Server allows an attacker to create smuggle or cache poison attacks. This issue affects Apache Traffic Server 8.0.0 to 9.1.2.
CVE-2021-40529 3 Botan Project, Fedoraproject, Mozilla 3 Botan, Fedora, Thunderbird 2022-12-09 2.6 LOW 5.9 MEDIUM
The ElGamal implementation in Botan through 2.18.1, as used in Thunderbird and other products, allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP.
CVE-2022-42799 3 Apple, Debian, Fedoraproject 8 Ipados, Iphone Os, Macos and 5 more 2022-12-08 N/A 6.1 MEDIUM
The issue was addressed with improved UI handling. This issue is fixed in tvOS 16.1, macOS Ventura 13, watchOS 9.1, Safari 16.1, iOS 16.1 and iPadOS 16. Visiting a malicious website may lead to user interface spoofing.
CVE-2022-34749 2 Fedoraproject, Mistune Project 2 Fedora, Mistune 2022-12-08 N/A 7.5 HIGH
In mistune through 2.0.2, support of inline markup is implemented by using regular expressions that can involve a high amount of backtracking on certain edge cases. This behavior is commonly named catastrophic backtracking.
CVE-2022-29221 3 Debian, Fedoraproject, Smarty 3 Debian Linux, Fedora, Smarty 2022-12-08 6.5 MEDIUM 8.8 HIGH
Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. Prior to versions 3.1.45 and 4.1.1, template authors could inject php code by choosing a malicious {block} name or {include} file name. Sites that cannot fully trust template authors should upgrade to versions 3.1.45 or 4.1.1 to receive a patch for this issue. There are currently no known workarounds.
