CVE-2021-35063 3 Debian, Fedoraproject, Oisf 3 Debian Linux, Fedora, Suricata 2026-06-17 5.0 MEDIUM 7.5 HIGH
Suricata before 5.0.7 and 6.x before 6.0.3 has a "critical evasion."
CVE-2021-35039 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-06-17 6.9 MEDIUM 7.8 HIGH
kernel/module.c in the Linux kernel before 5.12.14 mishandles Signature Verification, aka CID-0c18f29aae7c. Without CONFIG_MODULE_SIG, verification that a kernel module is signed, for loading via init_module, does not occur for a module.sig_enforce=1 command-line argument.
CVE-2021-34798 8 Apache, Broadcom, Debian and 5 more 18 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 15 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier.
CVE-2021-34552 3 Debian, Fedoraproject, Python 3 Debian Linux, Fedora, Pillow 2026-06-17 7.5 HIGH 9.8 CRITICAL
Pillow through 8.2.0 and PIL (aka Python Imaging Library) through 1.1.7 allow an attacker to pass controlled parameters directly into a convert function to trigger a buffer overflow in Convert.c.
CVE-2021-34428 4 Debian, Eclipse, Netapp and 1 more 16 Debian Linux, Jetty, Active Iq Unified Manager and 13 more 2026-06-17 3.6 LOW 2.9 LOW
For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, if an exception is thrown from the SessionListener#sessionDestroyed() method, then the session ID is not invalidated in the session ID manager. On deployments with clustered sessions and multiple contexts this can result in a session not being invalidated. This can result in an application used on a shared computer being left logged in.
CVE-2021-34334 3 Debian, Exiv2, Fedoraproject 3 Debian Linux, Exiv2, Fedora 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An infinite loop is triggered when Exiv2 is used to read the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. The bug is fixed in version v0.27.5.
CVE-2021-34055 2 Debian, Jhead Project 2 Debian Linux, Jhead 2026-06-17 N/A 7.8 HIGH
jhead 3.06 is vulnerable to Buffer Overflow via exif.c in function Put16u.
CVE-2021-33912 2 Debian, Libspf2 Project 2 Debian Linux, Libspf2 2026-06-17 9.3 HIGH 9.8 CRITICAL
libspf2 before 1.2.11 has a four-byte heap-based buffer overflow that might allow remote attackers to execute arbitrary code (via an unauthenticated e-mail message from anywhere on the Internet) with a crafted SPF DNS record, because of incorrect sprintf usage in SPF_record_expand_data in spf_expand.c. The vulnerable code may be part of the supply chain of a site's e-mail infrastructure (e.g., with additional configuration, Exim can use libspf2; the Postfix web site links to unofficial patches for use of libspf2 with Postfix; older versions of spfquery relied on libspf2) but most often is not.
CVE-2021-33909 6 Debian, Fedoraproject, Linux and 3 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2026-06-17 7.2 HIGH 7.8 HIGH
fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user, aka CID-8cae8cd89f05.
CVE-2021-33833 2 Debian, Intel 2 Debian Linux, Connection Manager 2026-06-17 7.5 HIGH 9.8 CRITICAL
ConnMan (aka Connection Manager) 1.30 through 1.39 has a stack-based buffer overflow in uncompress in dnsproxy.c via NAME, RDATA, or RDLENGTH (for A or AAAA).
CVE-2021-33829 4 Ckeditor, Debian, Drupal and 1 more 4 Ckeditor, Debian Linux, Drupal and 1 more 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
A cross-site scripting (XSS) vulnerability in the HTML Data Processor in CKEditor 4 4.14.0 through 4.16.x before 4.16.1 allows remote attackers to inject executable JavaScript code through a crafted comment because --!> is mishandled.
CVE-2021-33813 5 Apache, Debian, Fedoraproject and 2 more 6 Solr, Tika, Debian Linux and 3 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
An XXE issue in SAXBuilder in JDOM through 2.0.6 allows attackers to cause a denial of service via a crafted HTTP request.
CVE-2021-33623 3 Debian, Netapp, Trim-newlines Project 3 Debian Linux, E-series Performance Analyzer, Trim-newlines 2026-06-17 5.0 MEDIUM 7.5 HIGH
The trim-newlines package before 3.0.1 and 4.x before 4.0.1 for Node.js has an issue related to regular expression denial-of-service (ReDoS) for the .end() method.
CVE-2021-33620 3 Debian, Fedoraproject, Squid-cache 3 Debian Linux, Fedora, Squid 2026-06-17 4.0 MEDIUM 6.5 MEDIUM
Squid before 4.15 and 5.x before 5.0.6 allows remote servers to cause a denial of service (affecting availability to all clients) via an HTTP response. The issue trigger is a header that can be expected to exist in HTTP traffic without any malicious intent by the server.
CVE-2021-33582 3 Cyrus, Debian, Fedoraproject 3 Imap, Debian Linux, Fedora 2026-06-17 5.0 MEDIUM 7.5 HIGH
Cyrus IMAP before 3.4.2 allows remote attackers to cause a denial of service (multiple-minute daemon hang) via input that is mishandled during hash-table interaction. Because there are many insertions into a single bucket, strcmp becomes slow. This is fixed in 3.4.2, 3.2.8, and 3.0.16.
CVE-2021-33515 3 Debian, Dovecot, Fedoraproject 3 Debian Linux, Dovecot, Fedora 2026-06-17 5.8 MEDIUM 4.8 MEDIUM
The submission service in Dovecot before 2.3.15 allows STARTTLS command injection in lib-smtp. Sensitive information can be redirected to an attacker-controlled address.
CVE-2021-33477 6 Debian, Eterm Project, Fedoraproject and 3 more 6 Debian Linux, Eterm, Fedora and 3 more 2026-06-17 6.5 MEDIUM 8.8 HIGH
rxvt-unicode 9.22, rxvt 2.7.10, mrxvt 0.5.4, and Eterm 0.9.7 allow (potentially remote) code execution because of improper handling of certain escape sequences (ESC G Q). A response is terminated by a newline.
CVE-2021-33293 2 Debian, Libpano13 Project 2 Debian Linux, Libpano13 2026-06-17 6.4 MEDIUM 9.1 CRITICAL
Panorama Tools libpano13 v2.9.20 was discovered to contain an out-of-bounds read in the function panoParserFindOLine() in parser.c.
CVE-2021-33285 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2026-06-17 6.9 MEDIUM 7.8 HIGH
In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function ntfs_get_attribute_value, a heap buffer overflow can occur allowing for memory disclosure or denial of service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the "bytes_in_use" field should be less than the "bytes_allocated" field. When it is not, the parsing of the records proceeds into the wild.
CVE-2021-33196 2 Debian, Golang 2 Debian Linux, Go 2026-06-17 5.0 MEDIUM 7.5 HIGH
In archive/zip in Go before 1.15.13 and 1.16.x before 1.16.5, a crafted file count (in an archive's header) can cause a NewReader or OpenReader panic.
