CVE-2020-10957 1 Dovecot 1 Dovecot 2023-11-07 5.0 MEDIUM 7.5 HIGH
In Dovecot before 2.3.10.1, unauthenticated sending of malformed parameters to a NOOP command causes a NULL Pointer Dereference and crash in submission-login, submission, or lmtp.
CVE-2020-10739 1 Istio 1 Istio 2023-11-07 5.0 MEDIUM 7.5 HIGH
Istio 1.4.x before 1.4.9 and Istio 1.5.x before 1.5.4 contain the following vulnerability when telemetry v2 is enabled: by sending a specially crafted packet, an attacker could trigger a Null Pointer Exception resulting in a Denial of Service. This could be sent to the ingress gateway or a sidecar, triggering a null pointer exception which results in a denial of service. This also affects servicemesh-proxy where a null pointer exception flaw was found in servicemesh-proxy. When running Telemetry v2 (not on by default in version 1.4.x), an attacker could send a specially crafted packet to the ingress gateway or proxy sidecar, triggering a denial of service.
CVE-2020-10730 5 Debian, Fedoraproject, Opensuse and 2 more 5 Debian Linux, Fedora, Leap and 2 more 2023-11-07 4.0 MEDIUM 6.5 MEDIUM
A NULL pointer dereference, or possible use-after-free flaw was found in Samba AD LDAP server in versions before 4.10.17, before 4.11.11 and before 4.12.4. Although some versions of Samba shipped with Red Hat Enterprise Linux do not support Samba in AD mode, the affected code is shipped with the libldb package. This flaw allows an authenticated user to possibly trigger a use-after-free or NULL pointer dereference. The highest threat from this vulnerability is to system availability.
CVE-2020-10711 5 Canonical, Debian, Linux and 2 more 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more 2023-11-07 4.3 MEDIUM 5.9 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service.
CVE-2019-9937 1 Sqlite 1 Sqlite 2023-11-07 5.0 MEDIUM 7.5 HIGH
In SQLite 3.27.2, interleaving reads and writes in a single transaction with an fts5 virtual table will lead to a NULL Pointer Dereference in fts5ChunkIterate in sqlite3.c. This is related to ext/fts5/fts5_hash.c and ext/fts5/fts5_index.c.
CVE-2019-9923 2 Gnu, Opensuse 2 Tar, Leap 2023-11-07 5.0 MEDIUM 7.5 HIGH
pax_decode_header in sparse.c in GNU Tar before 1.32 had a NULL pointer dereference when parsing certain archives that have malformed extended headers.
