CVE-2021-43859 6 Debian, Fedoraproject, Jenkins and 3 more 14 Debian Linux, Fedora, Jenkins and 11 more 2025-11-03 7.5 High
XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible.

CVE-2021-3733 4 Fedoraproject, Netapp, Python and 1 more 21 Extra Packages For Enterprise Linux, Fedora, Hci Compute Node Firmware and 18 more 2025-11-03 6.5 Medium
There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability.
CVE-2021-3669 5 Debian, Fedoraproject, Ibm and 2 more 24 Debian Linux, Fedora, Spectrum Copy Data Management and 21 more 2025-11-03 5.5 Medium
A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS.
CVE-2021-3377 2 Ansi Up Project, Redhat 2 Ansi Up, Acm 2025-11-03 6.1 Medium
The npm package ansi_up converts ANSI escape codes into HTML. In ansi_up v4, ANSI escape codes can be used to create HTML hyperlinks. Due to insufficient URL sanitization, this feature is affected by a cross-site scripting (XSS) vulnerability. This issue is fixed in v5.0.0.
CVE-2021-38371 1 Exim 1 Exim 2025-11-03 7.5 High
The STARTTLS feature in Exim through 4.94.2 allows response injection (buffering) during MTA SMTP sending.
CVE-2021-37698 2 Debian, Icinga 2 Debian Linux, Icinga 2025-11-03 7.5 High
Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. In versions 2.5.0 through 2.13.0, ElasticsearchWriter, GelfWriter, InfluxdbWriter and Influxdb2Writer do not verify the server's certificate despite a certificate authority being specified. Icinga 2 instances which connect to any of the mentioned time series databases (TSDBs) using TLS over a spoofable infrastructure should immediately upgrade to version 2.13.1, 2.12.6, or 2.11.11 to patch the issue. Such instances should also change the credentials (if any) used by the TSDB writer feature to authenticate against the TSDB. There are no workarounds aside from upgrading.
CVE-2021-36976 4 Apple, Fedoraproject, Libarchive and 1 more 7 Ipados, Iphone Os, Macos and 4 more 2025-11-03 6.5 Medium
libarchive 3.4.1 through 3.5.1 has a use-after-free in copy_string (called from do_uncompress_block and process_block).
CVE-2021-36770 3 Fedoraproject, P5-encode Project, Perl 3 Fedora, P5-encode, Perl 2025-11-03 7.8 High
Encode.pm, as distributed in Perl through 5.34.0, allows local users to gain privileges via a Trojan horse Encode::ConfigLocal library (in the current working directory) that preempts dynamic module loading. Exploitation requires an unusual configuration, and certain 2021 versions of Encode.pm (3.05 through 3.11). This issue occurs because the || operator evaluates @INC in a scalar context, and thus @INC has only an integer value.
CVE-2021-36690 3 Apple, Oracle, Sqlite 6 Iphone Os, Macos, Tvos and 3 more 2025-11-03 7.5 High
A segmentation fault can occur in the sqlite3.exe command-line component of SQLite 3.36.0 via the idxGetTableInfo function when there is a crafted SQL query. NOTE: the vendor disputes the relevance of this report because a sqlite3.exe user already has full privileges (e.g., is intentionally allowed to execute commands). This report does NOT imply any problem in the SQLite library.
CVE-2021-36087 3 Fedoraproject, Redhat, Selinux Project 3 Fedora, Enterprise Linux, Selinux 2025-11-03 3.3 Low
The CIL compiler in SELinux 3.2 has a heap-based buffer over-read in ebitmap_match_any (called indirectly from cil_check_neverallow). This occurs because there is sometimes a lack of checks for invalid statements in an optional block.
CVE-2021-36086 3 Fedoraproject, Redhat, Selinux Project 3 Fedora, Enterprise Linux, Selinux 2025-11-03 3.3 Low
The CIL compiler in SELinux 3.2 has a use-after-free in cil_reset_classpermission (called from cil_reset_classperms_set and cil_reset_classperms_list).
CVE-2021-36085 3 Fedoraproject, Redhat, Selinux Project 3 Fedora, Enterprise Linux, Selinux 2025-11-03 3.3 Low
The CIL compiler in SELinux 3.2 has a use-after-free in __cil_verify_classperms (called from __verify_map_perm_classperms and hashtab_map).
CVE-2021-36084 3 Fedoraproject, Redhat, Selinux Project 3 Fedora, Enterprise Linux, Selinux 2025-11-03 3.3 Low
The CIL compiler in SELinux 3.2 has a use-after-free in __cil_verify_classperms (called from __cil_verify_classpermission and __cil_pre_verify_helper).
CVE-2021-34193 1 Opensc Project 1 Opensc 2025-11-03 7.5 High
Stack overflow vulnerability in OpenSC smart card middleware before 0.23 via crafted responses to APDUs.
CVE-2021-32839 2 Redhat, Sqlparse Project 3 Satellite, Satellite Capsule, Sqlparse 2025-11-03 7.5 High
sqlparse is a non-validating SQL parser module for Python. In sqlparse versions 0.4.0 and 0.4.1 there is a regular Expression Denial of Service in sqlparse vulnerability. The regular expression may cause exponential backtracking on strings containing many repetitions of '\r\n' in SQL comments. Only the formatting feature that removes comments from SQL statements is affected by this regular expression. As a workaround don't use the sqlformat.format function with keyword strip_comments=True or the --strip-comments command line flag when using the sqlformat command line tool. The issues has been fixed in sqlparse 0.4.2.
