CVE-2021-3739 3 Fedoraproject, Linux, Netapp 18 Fedora, Linux Kernel, H300e and 15 more 2024-11-21 3.6 LOW 7.1 HIGH
A NULL pointer dereference flaw was found in the btrfs_rm_device function in fs/btrfs/volumes.c in the Linux Kernel, where triggering the bug requires ‘CAP_SYS_ADMIN’. This flaw allows a local attacker to crash the system or leak kernel internal information. The highest threat from this vulnerability is to system availability.
CVE-2021-3671 3 Debian, Netapp, Samba 5 Debian Linux, Management Services For Element Software, Management Services For Netapp Hci and 2 more 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server.
CVE-2021-3659 3 Fedoraproject, Linux, Redhat 17 Fedora, Linux Kernel, Codeready Linux Builder and 14 more 2024-11-21 N/A 5.5 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability.
CVE-2021-3596 4 Debian, Fedoraproject, Imagemagick and 1 more 4 Debian Linux, Fedora, Imagemagick and 1 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage() in coders/svg.c. This issue is due to not checking the return value from libxml2's xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.
CVE-2021-3543 3 Fedoraproject, Nitro Enclaves Project, Redhat 3 Fedora, Nitro Enclaves, Enterprise Linux 2024-11-21 7.2 HIGH 6.7 MEDIUM
A flaw null pointer dereference in the Nitro Enclaves kernel driver was found in the way that Enclaves VMs forces closures on the enclave file descriptor. A local user of a host machine could use this flaw to crash the system or escalate their privileges on the system.
CVE-2021-3537 6 Debian, Fedoraproject, Netapp and 3 more 20 Debian Linux, Fedora, Active Iq Unified Manager and 17 more 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability.
CVE-2021-3514 1 Redhat 1 389 Directory Server 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
When using a sync_repl client in 389-ds-base, an authenticated attacker can cause a NULL pointer dereference using a specially crafted query, causing a crash.
CVE-2021-3480 2 Fedoraproject, Slapi-nis Project 2 Fedora, Slapi-nis 2024-11-21 5.0 MEDIUM 7.5 HIGH
A flaw was found in slapi-nis in versions before 0.56.7. A NULL pointer dereference during the parsing of the Binding DN could allow an unauthenticated attacker to crash the 389-ds-base directory server. The highest threat from this vulnerability is to system availability.
CVE-2021-3467 2 Fedoraproject, Jasper Project 2 Fedora, Jasper 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A NULL pointer dereference flaw was found in the way Jasper versions before 2.0.26 handled component references in CDEF box in the JP2 image format decoder. A specially crafted JP2 image file could cause an application using the Jasper library to crash when opened.
CVE-2021-3463 1 Lenovo 125 Power Management Driver, Thinkpad 11e Gen 5, Thinkpad 11e Yoga Gen 6 and 122 more 2024-11-21 4.9 MEDIUM 4.2 MEDIUM
A null pointer dereference vulnerability in Lenovo Power Management Driver for Windows 10, prior to version 1.67.17.54, that could cause systems to experience a blue screen error.
CVE-2021-3449 12 Checkpoint, Debian, Fedoraproject and 9 more 167 Multi-domain Management, Multi-domain Management Firmware, Quantum Security Gateway and 164 more 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).
CVE-2021-3443 3 Fedoraproject, Jasper Project, Redhat 3 Fedora, Jasper, Enterprise Linux 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A NULL pointer dereference flaw was found in the way Jasper versions before 2.0.27 handled component references in the JP2 image format decoder. A specially crafted JP2 image file could cause an application using the Jasper library to crash when opened.
