GNOME libxml2 is vulnerable to a buffer overflow, caused by improper bounds checking by the xmlEncodeEntitiesInternal function in libxml2/entities.c. By persuading a victim to open a specially-crafted file, a remote attacker could overflow a buffer and execute arbitrary code on the system.

A vulnerability was found in Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created.

GNU ncurses could allow a remote attacker to obtain sensitive information, caused by a heap-based buffer over-read in the ncfindentry function in tinfo/comphash.c in the terminfo library. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to obtain sensitive information.

GNU ncurses could allow a remote attacker to obtain sensitive information, caused by a heap-based buffer over-read in the fmtentry function in tinfo/comphash.c in the terminfo library. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to obtain sensitive information.

It was discovered that there was a ECDSA timing attack in the libgcrypt20 cryptographic library. Version affected: 1.8.4-5, 1.7.6-2+deb9u3, and 1.6.3-2+deb8u4. Versions fixed: 1.8.5-2 and 1.6.3-2+deb8u7.

An issue was discovered in the server in OpenLDAP before 2.4.48. When the server administrator delegates rootDN (database admin) privileges for certain databases but wants to maintain isolation (e.g., for multi-tenant deployments), slapd does not properly stop a rootDN from requesting authorization as an identity from another database during a SASL bind or with a proxyAuthz (RFC 4370) control. (It is not a common configuration to deploy a system where the server administrator and a DB administrator enjoy different levels of trust.)

Double Free in VLC versions <= 3.0.6 leads to a crash.

An integer overflow was found in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. As per upstream: No EC algorithms are affected. Attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low level API BNmodexp may be affected if they use BNFLGCONSTTIME

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in bfddoprnt in bfd.c because elfobjectp in elfcode.h mishandles an eshstrndx section of type SHTGROUP by omitting a trailing '\0' character.

A flaw was found in nodejs-minimist, where it was tricked into adding or modifying properties of the Object.prototype using a "constructor" or "proto" payload. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

A flaw was found in Apache Tomcat. The HTTP header parsing code used an approach to end-of-line (EOL) parsing that allowed some invalid HTTP headers to be parsed as valid. This led to the possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. The highest threat with this vulnerability is system availability.

In the Linux kernel before 5.4.16, a race condition in tty->discdata handling in the slip and slcan line discipline could lead to a use-after-free, aka CID-0ace17d56824. This affects drivers/net/slip/slip.c and drivers/net/can/slcan.c.

An issue was discovered in the Linux kernel before 5.4.17. drivers/spi/spi-dw.c allows attackers to cause a panic via concurrent calls to dwspiirq and dwspitransferone, aka CID-19b61392c5a8.

An issue was discovered in slcbump in drivers/net/can/slcan.c in the Linux kernel 3.16 through 5.6.2. It allows attackers to read uninitialized canframe data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIGINITSTACKALL, aka CID-b9258a2cece4.

A use-after-free flaw was found in the acmprobe USB subsystem in the Linux kernel. A race condition occurs when a destroy() procedure is initiated allowing the refcount to decrement on the interface so early that it is never under counted. A malicious USB device is required for exploit. System availability is the largest threat from the vulnerability, however data integrity and confidentiality are also threatened.

A flaw was found in the Linux kernel's mwifiex driver implementation when connecting to other WiFi devices in "Test Mode." A kernel memory leak can occur if an error condition is met during the parameter negotiation. This issue can lead to a denial of service if multiple error conditions meeting the repeated connection attempts are attempted.

In the Linux kernel through 5.4.6, there is a NULL pointer dereference in drivers/scsi/libsas/sasdiscover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition, aka CID-f70267f379b5.

Four memory leaks in the nfpflowerspawnphyreprs() function in drivers/net/ethernet/netronome/nfp/flower/main.c in the Linux kernel before 5.3.4 allow attackers to cause a denial of service (memory consumption), aka CID-8572cea1461a.

A memory leak in the nfpflowerspawnvnicreprs() function in drivers/net/ethernet/netronome/nfp/flower/main.c in the Linux kernel before 5.3.4 allows attackers to cause a denial of service (memory consumption), aka CID-8ce39eb5a67a.

A memory leak in the cx23888irprobe() function in drivers/media/pci/cx23885/cx23888-ir.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering kfifoalloc() failures, aka CID-a7b2df76b42b.

A memory leak in the bfadimgetstats() function in drivers/scsi/bfa/bfadattr.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering bfaportgetstats() failures, aka CID-0e62395da2bd.

An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/sisusbvga/sisusb.c driver.

A vulnerability was found in the Linux kernel. The Zr364xx USB device driver is susceptible to malicious USB devices. An attacker able to add a specific USB device could cause a crash leading to a denial of service.

An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/siano/smsusb.c driver.

An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. simpleobjectelfmatch in simple-object-elf.c does not check for a zero shstrndx value, leading to an integer overflow and resultant heap-based buffer overflow.
