CVE-2021-40153 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2026-06-17 5.8 MEDIUM 8.1 HIGH
squashfs_opendir in unsquash-1.c in Squashfs-Tools 4.5 stores the filename in the directory entry; this is then used by unsquashfs to create the new file during the unsquash. The filename is not validated for traversal outside of the destination directory, and thus allows writing to locations outside of the destination.
CVE-2021-40085 2 Debian, Openstack 2 Debian Linux, Neutron 2026-06-17 4.0 MEDIUM 6.5 MEDIUM
An issue was discovered in OpenStack Neutron before 16.4.1, 17.x before 17.2.1, and 18.x before 18.1.1. Authenticated attackers can reconfigure dnsmasq via a crafted extra_dhcp_opts value.
CVE-2021-3984 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2026-06-17 6.8 MEDIUM 7.8 HIGH
vim is vulnerable to Heap-based Buffer Overflow
CVE-2021-3975 5 Canonical, Debian, Fedoraproject and 2 more 14 Ubuntu Linux, Debian Linux, Fedora and 11 more 2026-06-17 N/A 6.5 MEDIUM
A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash.
CVE-2021-3941 4 Debian, Fedoraproject, Openexr and 1 more 4 Debian Linux, Fedora, Openexr and 1 more 2026-06-17 2.1 LOW 6.5 MEDIUM
In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR.
CVE-2021-3935 4 Debian, Fedoraproject, Pgbouncer and 1 more 4 Debian Linux, Fedora, Pgbouncer and 1 more 2026-06-17 5.1 MEDIUM 8.1 HIGH
When PgBouncer is configured to use "cert" authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of TLS certificate verification and encryption. This flaw affects PgBouncer versions prior to 1.16.1.
CVE-2021-3933 3 Debian, Fedoraproject, Openexr 3 Debian Linux, Fedora, Openexr 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
An integer overflow could occur when OpenEXR processes a crafted file on systems where size_t < 64 bits. This could cause an invalid bytesPerLine and maxBytesPerLine value, which could lead to problems with application stability or lead to other attack paths.
CVE-2021-3930 3 Debian, Qemu, Redhat 10 Debian Linux, Qemu, Codeready Linux Builder and 7 more 2026-06-17 2.1 LOW 6.5 MEDIUM
An off-by-one error was found in the SCSI device emulation in QEMU. It could occur while processing MODE SELECT commands in mode_sense_page() if the 'page' argument was set to MODE_PAGE_ALLS (0x3f). A malicious guest could use this flaw to potentially crash QEMU, resulting in a denial of service condition.
CVE-2021-3918 2 Debian, Json-schema Project 2 Debian Linux, Json-schema 2026-06-17 7.5 HIGH 9.8 CRITICAL
json-schema is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')
CVE-2021-3912 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2026-06-17 4.3 MEDIUM 4.2 MEDIUM
OctoRPKI tries to load the entire contents of a repository in memory, and in the case of a GZIP bomb, unzip it in memory, making it possible to create a repository that makes OctoRPKI run out of memory (and thus crash).
CVE-2021-3911 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2026-06-17 4.3 MEDIUM 4.2 MEDIUM
If the ROA that a repository returns contains too many bits for the IP address then OctoRPKI will crash.
CVE-2021-3910 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2026-06-17 5.0 MEDIUM 4.4 MEDIUM
OctoRPKI crashes when encountering a repository that returns an invalid ROA (just an encoded NUL (\0) character).
CVE-2021-3909 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2026-06-17 5.0 MEDIUM 4.4 MEDIUM
OctoRPKI does not limit the length of a connection, allowing for a slowloris DOS attack to take place which makes OctoRPKI wait forever. Specifically, the repository that OctoRPKI sends HTTP requests to will keep the connection open for a day before a response is returned, but does keep drip feeding new bytes to keep the connection alive.
CVE-2021-3908 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2026-06-17 5.0 MEDIUM 5.9 MEDIUM
OctoRPKI does not limit the depth of a certificate chain, allowing for a CA to create children in an ad-hoc fashion, thereby making tree traversal never end.
CVE-2021-3907 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2026-06-17 7.5 HIGH 7.4 HIGH
OctoRPKI does not escape a URI with a filename containing "..", this allows a repository to create a file, (ex. rsync://example.org/repo/../../etc/cron.daily/evil.roa), which would then be written to disk outside the base cache folder. This could allow for remote code execution on the host machine OctoRPKI is running on.
CVE-2021-3903 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2026-06-17 4.6 MEDIUM 7.8 HIGH
vim is vulnerable to Heap-based Buffer Overflow
CVE-2021-3872 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2026-06-17 6.8 MEDIUM 7.8 HIGH
vim is vulnerable to Heap-based Buffer Overflow
CVE-2021-3864 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2026-06-17 N/A 7.0 HIGH
A flaw was found in the way the dumpable flag setting was handled when certain SUID binaries executed its descendants. The prerequisite is a SUID binary that sets real UID equal to effective UID, and real GID equal to effective GID. The descendant will then have a dumpable value set to 1. As a result, if the descendant process crashes and core_pattern is set to a relative value, its core dump is stored in the current directory with uid:gid permissions. An unprivileged local user with eligible root SUID binary could use this flaw to place core dumps into root-owned directories, potentially resulting in escalation of privileges.
CVE-2021-3850 2 Adodb Project, Debian 2 Adodb, Debian Linux 2026-06-17 6.4 MEDIUM 9.1 CRITICAL
Authentication Bypass by Primary Weakness in GitHub repository adodb/adodb prior to 5.20.21.
CVE-2021-3842 3 Debian, Fedoraproject, Nltk 3 Debian Linux, Fedora, Nltk 2026-06-17 5.0 MEDIUM 7.5 HIGH
nltk is vulnerable to Inefficient Regular Expression Complexity
