In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, asynchronous callbacks received a pointer to a callers local variable. Should the caller return early (e.g., timeout), the callback will dereference an invalid pointer.

subversion: malicious SVN clients can crash mod_dav_svn

Subversion's mod_dav_svn Apache HTTPD module versions 1.11.0 and 1.10.0 to 1.10.3 will crash after dereferencing an uninitialized pointer if the client omits the root path in a recursive directory listing operation.

An issue was discovered in LibSass through 3.5.4. A NULL pointer dereference was found in the function Sass::Inspect::operator which could be leveraged by an attacker to cause a denial of service (application crash) or possibly have unspecified other impact.

An issue was discovered in LibSass <3.5.3. A NULL pointer dereference was found in the function Sass::Expand::operator which could be leveraged by an attacker to cause a denial of service (application crash) or possibly have unspecified other impact.

An issue was discovered in LibSass through 3.5.4. A NULL pointer dereference was found in the function Sass::Functions::selector_append which could be leveraged by an attacker to cause a denial of service (application crash) or possibly have unspecified other impact.

Espruino before 1.98 allows attackers to cause a denial of service (application crash) with a user crafted input file via a NULL pointer dereference during syntax parsing. This was addressed by adding validation for a debug trace print statement in jsvar.c.

wireshark: Out-of-bounds Read in proto.c

In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the RRC dissector and other dissectors could crash. This was addressed in epan/proto.c by avoiding a NULL pointer dereference.

wireshark: DNS dissector crash in packet-dns.c

In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the DNS dissector could crash. This was addressed in epan/dissectors/packet-dns.c by avoiding a NULL pointer dereference for an empty name in an SRV record.

An issue was discovered in PoDoFo 0.9.5. The function PdfDocument::Append() in PdfDocument.cpp in PoDoFo 0.9.5 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted PDF document.

An issue was discovered in PoDoFo 0.9.5. The function PdfPage::GetPageNumber() in PdfPage.cpp in PoDoFo 0.9.5 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted PDF document.

hdf5: NULL pointer dereference in H5O__chunk_deserialize in H5Ocache.c

A NULL pointer dereference was discovered in H5O__chunk_deserialize in H5Ocache.c in the HDF HDF5 1.10.2 library. It could allow a remote denial of service attack.

hdf5: NULL pointer dereference in H5S_hyper_make_spans in H5Shyper.c

A NULL pointer dereference was discovered in H5S_hyper_make_spans in H5Shyper.c in the HDF HDF5 1.10.2 library. It could allow a remote denial of service attack.

The mg_handle_cgi function in mongoose.c in Mongoose 6.11 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash, or NULL pointer dereference) via an HTTP request, related to the mbuf_insert function.

samba: DsCrackNames on a user without an SPN can trigger NULL-pointer de-reference

A null pointer dereference flaw was found in the way samba checked database outputs from the LDB database layer. An authenticated attacker could use this flaw to crash a samba server in an Active Directory Domain Controller configuration. Samba versions before 4.7.9 and 4.8.4 are vulnerable.

glusterfs: remote denial of service of gluster volumes via posix_get_file_contents function in posix-helpers.c

It was found that an attacker could issue a xattr request via glusterfs FUSE to cause gluster brick process to crash which will result in a remote denial of service. If gluster multiplexing is enabled this will result in a crash of multiple bricks and gluster volumes.

bibutils: NULL pointer dereference in _fields_add function in fields.c in libbibcore.a

NULL pointer dereference in the _fields_add function in fields.c in libbibcore.a in bibutils through 6.2 allows remote attackers to cause a denial of service (application crash), as demonstrated by end2xml.

bibutils: NULL pointer deference in addsn function in serialno.c in libbibcore.a

NULL pointer deference in the addsn function in serialno.c in libbibcore.a in bibutils through 6.2 allows remote attackers to cause a denial of service (application crash), as demonstrated by copac2xml.

poppler: NULL pointer dereference in Annot.h:AnnotPath::getCoordsLength() allows for denial of service via crafted PDF

There is a NULL pointer dereference in the AnnotPath::getCoordsLength function in Annot.h in an Ubuntu package for Poppler 0.24.5. A crafted input will lead to a remote denial of service attack. Later Ubuntu packages such as for Poppler 0.41.0 are not affected.

php: NULL pointer dereference due to mishandling of ldap_get_dn return value allows DoS via malicious LDAP server reply

An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. ext/ldap/ldap.c allows remote LDAP servers to cause a denial of service (NULL pointer dereference and application crash) because of mishandling of the ldap_get_dn return value.

binutils: NULL pointer dereference in elf.c

The ignore_section_sym function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, does not validate the output_section pointer in the case of a symtab entry with a "SECTION" type that has a "0" value, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted file, as demonstrated by objcopy.
