A vulnerability was found in sssd where, if a user was configured with no home directory set, sssd would return '/' (the root directory) instead of '' (the empty string / no home directory). This could impact services that restrict the user's filesystem access to within their home directory through chroot().

Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response.

A flaw was found in the Linux kernel vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS).

A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network.

An issue was discovered in fs/f2fs/super.c in the Linux kernel through 4.14. A denial of service (out-of-bounds memory access and BUG) can occur upon encountering an abnormal bitmap size when mounting a crafted f2fs image.

A flaw was found in the kernels implementation of the bluetooth HIDP (Human Interface Device Protocol). A local attacker with access permissions to the bluetooth device can issue an IOCTL which will trigger the dohidpsockioctl function in net/bluetooth/hidp/sock.c.c. This function can potentially leak potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not correctly NULL terminated.

The Siemens R3964 line discipline driver in drivers/tty/nr3964.c in the Linux kernel before 5.0.8 has multiple race conditions.

A vulnerability was found in Python 2.7.x through 2.7.16 and 3.x through 3.7.2. An improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization could lead to an Information Disclosure (credentials, cookies, etc. that are cached against a given hostname) in the urllib.parse.urlsplit, urllib.parse.urlparse components. A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly.

An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exifprocessIFDinMAKERNOTE because of mishandling the makernote->offset relationship to valuelen.

A use-after-free vulnerability was discovered in the pngimagefree function in the libpng library. This could lead to denial of service or a potentially exploitable crash when a malformed image is processed.

A flaw was found in the BigDecimal implementation in the Libraries component of OpenJDK. An untrusted numeric value parsed by a Java application could the application to use an excessive amount of CPU time.

A flaw was found in the RMI registry implementation in the RMI component of OpenJDK. Incorrect handling of the server-side dispatch could lead to selection of an incorrect skeleton class.

An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an Invalid Read in exifprocessSOFn.

Fixed bug (Heap-buffer-overflow in estrndup via exifprocessIFDTAG) (CVE-2019-11036).

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. A heap-based buffer over-read in PHAR reading functions in the PHAR extension may allow an attacker to read allocated or unallocated memory past the actual data when trying to parse the file name, a different vulnerability than CVE-2018-20783. This is related to phardetectpharfnameext in ext/phar/phar.c.

An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exifprocessIFDinTIFF.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the GSS-API dissector could crash. This was addressed in epan/dissectors/packet-gssapi.c by ensuring that a valid dissector is called.

Cacti through 1.2.7 is affected by multiple instances of lib/functions.php unsafe deserialization of user-controlled data to populate arrays. An authenticated attacker could use this to influence object data values and control actions taken by Cacti or potentially cause memory corruption in the PHP module.

A vulnerability in the Object Linking & Embedding (OLE2) file scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms for OLE2 files sent an affected device. An attacker could exploit this vulnerability by sending malformed OLE2 files to the device running an affected version ClamAV Software. An exploit could allow the attacker to cause an out-of-bounds write condition, resulting in a crash that could result in a denial of service condition on an affected device.

urllib in Python 2.x through 2.7.16 supports the localfile: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen('localfile:///etc/passwd') call.

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. A number of heap-based buffer over-read instances are present in mbstring regular expression functions when supplied with invalid multibyte data. These occur in ext/mbstring/oniguruma/regcomp.c, ext/mbstring/oniguruma/regexec.c, ext/mbstring/oniguruma/regparse.c, ext/mbstring/oniguruma/enc/unicode.c, and ext/mbstring/oniguruma/src/utf32be.c when a multibyte regular expression pattern contains invalid multibyte sequences.

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. xmlrpcdecode() can allow a hostile XMLRPC server to cause PHP to read memory outside of allocated areas in base64decodexmlrpc in ext/xmlrpc/libxmlrpc/base64.c.

An issue was discovered in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. Due to the way rename() across filesystems is implemented, it is possible that file being renamed is briefly available with wrong permissions while the rename is ongoing, thus enabling unauthorized users to access the data.

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 xmlrpcdecode() can lead to an invalid memory access (heap out of bounds read or read after free). This is related to xmlelemparsebuf in ext/xmlrpc/libxmlrpc/xmlelement.c.

An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exifprocessIFDinMAKERNOTE because of mishandling the datalen variable.

In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the ASN.1 BER and related dissectors could crash. This was addressed in epan/dissectors/packet-ber.c by preventing a buffer overflow associated with excessive digits in time values.
