Various Lexmark products have a Buffer Overflow (issue 2 of 3).

In PuTTY versions before 0.71 on Unix, a remotely triggerable buffer overflow exists in any kind of server-to-client forwarding.

Mozilla: Improper bounds checks when Spectre mitigations are disabled

A mechanism was discovered that removes some bounds checking for string, array, or typed array accesses if Spectre mitigations have been disabled. This vulnerability could allow an attacker to create an arbitrary value in compiled JavaScript, for which the range analysis will infer a fully controlled, incorrect range in circumstances where users have explicitly disabled Spectre mitigations. *Note: Spectre mitigations are currently enabled for all users by default settings.*. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.

Buffer overflow vulnerability found in some Dahua IP Camera devices IPC-HFW1XXX,IPC-HDW1XXX,IPC-HFW2XXX Build before 2018/11. The vulnerability exits in the function of redirection display for serial port printing information, which can not be used by product basic functions. After an attacker logs in locally, this vulnerability can be exploited to cause device restart or arbitrary code execution. Dahua has identified the corresponding security problems in the static code auditing process, so it has gradually deleted this function, which is no longer available in the newer devices and softwares. Dahua has released versions of the affected products to fix the vulnerability.

php: buffer overflow in ext/phar/tar.c

An issue was discovered in PHP 7.x before 7.1.27 and 7.3.x before 7.3.3. phar_tar_writeheaders_int in ext/phar/tar.c has a buffer overflow via a long link value. NOTE: The vendor indicates that the link value is used only when an archive contains a symlink, which currently cannot happen: "This issue allows theoretical compromise of security, but a practical attack is usually impossible.

There is an Invalid memory access in gAtomicIncrement() located at GMutex.h in Xpdf 4.01. It can be triggered by sending a crafted pdf file to (for example) the pdftops binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.

kernel: OOB write due to missing bounds check leads to local privilege escalation

In the Android kernel in Pixel C USB monitor driver there is a possible OOB write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.

kernel: out of bounds write in i2c driver leads to local escalation of privilege

In the Android kernel in i2c driver there is a possible out of bounds write due to memory corruption. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.

opencv: Out of bounds write due to missing bounds check

In opencv calls that use libpng, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges required. User interaction is not required for exploitation. Product: AndroidVersions: Android-10Android ID: A-110986616

kernel: out-of-bounds read/write in et/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP NAT module

In the Linux kernel before 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP NAT module has insufficient ASN.1 length checks (aka an array index error), making out-of-bounds read and write operations possible, leading to an OOPS or local privilege escalation. This affects snmp_version and snmp_helper.

php: memcpy with negative length via crafted DNS response

An issue was discovered in PHP 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.2. dns_get_record misparses a DNS response, which can allow a hostile DNS server to cause PHP to misuse memcpy, leading to read operations going past the buffer allocated for DNS data. This affects php_parserr in ext/standard/dns.c for DNS_CAA and DNS_ANY queries.

php: Invalid memory access in function xmlrpc_decode()

An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. Invalid input to the function xmlrpc_decode() can lead to an invalid memory access (heap out of bounds read or read after free). This is related to xml_elem_parse_buf in ext/xmlrpc/libxmlrpc/xml_element.c.

The British Airways Entertainment System, as installed on Boeing 777-36N(ER) and possibly other aircraft, does not prevent the USB charging/data-transfer feature from interacting with USB keyboard and mouse devices, which allows physically proximate attackers to conduct unanticipated attacks against Entertainment applications, as demonstrated by using mouse copy-and-paste actions to trigger a Chat buffer overflow or possibly have unspecified other impact.

In Signiant Manager+Agents before 13.5, the implementation of the set command has a Buffer Overflow.

ntp: Crafted null dereference attack in authenticated mode 6 packet

NTP through 4.2.8p12 has a NULL Pointer Dereference.
