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.

An infinite loop issue was found in the vhostnet kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handlerx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhostnet kernel thread, resulting in a DoS scenario.

In Pallets Jinja before 2.10.1, str.formatmap allows a sandbox escape.

The sandbox is used to restrict what code can be evaluated when rendering untrusted, user-provided templates. Due to the way string formatting works in Python, the str.formatmap method could be used to escape the sandbox.

This issue was previously addressed for the str.format method in Jinja 2.8.1, which discusses the issue in detail. However, the less-common str.formatmap method was overlooked. This release applies the same sandboxing to both methods.

If you cannot upgrade Jinja, you can override the issafeattribute method on the sandbox and explicitly disallow the formatmap method on string objects.

Apache HTTP Server, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute code with the privileges of the parent process (usually root) by manipulating the scoreboard.

A race condition was found in modauthdigest when the web server was running in a threaded MPM configuration. It could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions.

A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account for duplicates in regular expressions while other aspects of the servers processing will implicitly collapse them.

A Prototype Pollution vulnerability was found in jquery. Untrusted JSON passed to the extend function could lead to modifying objects up the prototype chain, including the global Object. A crafted JSON object passed to a vulnerable method could lead to denial of service or data injection, with various consequences.

An out of bounds read flaw was discovered in libssh2 before 1.8.1 in the libssh2packetrequire and libssh2packetrequirev functions. A remote attacker who compromises a SSH server may be able to cause a Denial of Service or read data in the client memory.

An issue was discovered in Qt 5.11. A malformed PPM image causes a division by zero and a crash in qppmhandler.cpp.

A malicious server could send a specially crafted packet which could result in an unchecked integer overflow. The value would then be used to allocate memory causing a possible memory write out of bounds error.

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.

It was discovered in gnutls before version 3.6.7 upstream that there is an uninitialized pointer access in gnutls versions 3.6.3 or later which can be triggered by certain post-handshake messages.

Django 1.11.x before 1.11.19, 2.0.x before 2.0.11, and 2.1.x before 2.1.6 allows Uncontrolled Memory Consumption via a malicious attacker-supplied value to the django.utils.numberformat.format() function.

CVE-2019-1000020 libarchive version commit 5a98dcf8a86364b3c2c469c85b93647dfb139961 onwards (version v2.8.0 onwards) contains a CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in ISO9660 parser, archivereadsupportformatiso9660.c, readCE()/parserockridge() that can result in DoS by infinite loop. This attack appears to be exploitable via the victim opening a specially crafted ISO9660 file. CVE-2019-1000019 libarchive version commit bf9aec176c6748f0ee7a678c5f9f9555b9a757c1 onwards (release v3.0.2 onwards) contains a CWE-125: Out-of-bounds Read vulnerability in 7zip decompression, archivereadsupportformat7zip.c, headerbytes() that can result in a crash (denial of service). This attack appears to be exploitable via the victim opening a specially crafted 7zip file.

In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo.

An information leakage issue was found in the way Linux kernel's KVM hypervisor handled page fault exception while emulating instructions like VMXON, VMCLEAR, VMPTRLD, VMWRITE with memory address as an operand. It occurs if the operand is an mmio address, as the returned exception object holds uninitialised stack memory contents.

A guest user/process could use this flaw to leak host's stack memory contents to a guest.

It affects only Intel processors and only when nested virtualization is enabled.

A use after free issue was found in the way Linux kernel's KVM hypervisor emulates a preemption timer for L2 guest when nested(=1) virtualization is enabled. This high resolution timer(hrtimer) runs when L2 guest is active. After VM exit, in syncvmcs12() timer object is stopped. The use-after-free occurs if the timer object is free'd before calling syncvmcs12() routine.

A guest user/process could use this flaw to crash the host kernel resulting in DoS OR potentially gain privileged access to a system.

It affects only Intel processors and only when nested virtualization is enabled.
