tomcat: non-persistent DoS attack by feeding data by aborting an upload

Apache Tomcat 6.x before 6.0.44, 7.x before 7.0.55, and 8.x before 8.0.9 does not properly handle cases where an HTTP response occurs before finishing the reading of an entire request body, which allows remote attackers to cause a denial of service (thread consumption) via a series of aborted upload attempts.

python: Information Disclosure due to urlsplit improper NFKC normalization

Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. The attack vector is: 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. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9.

jackson-databind: Deserialization vulnerability via readValue method of ObjectMapper

A deserialization flaw was discovered in the jackson-databind, versions before 2.6.7.1, 2.7.9.1 and 2.8.9, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper.

kernel: FUSE allows UAF reads of write() buffers, allowing theft of (partial) /etc/shadow hashes

A use-after-free flaw was found in the Linux kernel’s FUSE filesystem in the way a user triggers write(). This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation.

hw: cpu: speculative store bypass

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.

hw: TSX Transaction Asynchronous Abort (TAA)

TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.

bash: specially-crafted environment variables can be used to inject shell commands

GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix.

bash: code execution via specially-crafted environment (Incomplete fix for CVE-2014-6271)

GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.

bouncycastle: flaw in the low-level interface to RSA key pair generator

Bouncy Castle BC 1.54 - 1.59, BC-FJA 1.0.0, BC-FJA 1.0.1 and earlier have a flaw in the Low-level interface to RSA key pair generator, specifically RSA Key Pairs generated in low-level API with added certainty may have less M-R tests than expected. This appears to be fixed in versions BC 1.60 beta 4 and later, BC-FJA 1.0.2 and later.

Qemu: net: pcnet: buffer overflow in non-loopback mode

Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet.

Unspecified vulnerability in the Oracle Secure Global Desktop (SGD) component in Oracle Virtualization 5.0 and 5.1 allows remote attackers to affect confidentiality and integrity via unknown vectors related to Workspace Web Application.

Unspecified vulnerability in Oracle Virtualization Sun Ray Software before 5.4.4 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Web Console.

Unspecified vulnerability in the Oracle Secure Global Desktop (SGD) component in Oracle Virtualization 4.63, 4.71, 5.0, and 5.1 allows remote attackers to affect integrity via unknown vectors related to Workspace Web Application, a different vulnerability than CVE-2014-4232.

Unspecified vulnerability in the Oracle Secure Global Desktop component in Oracle Virtualization 5.0 and 5.1 allows remote attackers to affect availability via vectors related to SGD Proxy Server (ttaauxserv), a different vulnerability than CVE-2014-2474, CVE-2014-2476, and CVE-2014-6459.

Qemu: rtl8139 uninitialized heap memory information leakage to guest (XSA-140)

The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors.

qemu: incorrect banked access bounds checking in vga module

The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue.

Unspecified vulnerability in the Oracle Secure Global Desktop (SGD) component in Oracle Virtualization 4.63, 4.71, 5.0, and 5.1 allows remote attackers to affect integrity via unknown vectors related to Workspace Web Application, a different vulnerability than CVE-2014-2463.

glibc: __nss_hostname_digits_dots() heap-based buffer overflow

Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST."

qemu: vnc: insufficient resource limiting in VNC websockets decoder

The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and CPU consumption) via a large (1) websocket payload or (2) HTTP headers section.

Unspecified vulnerability in the Oracle Secure Global Desktop component in Oracle Virtualization 5.0 and 5.1 allows remote attackers to affect availability via vectors related to SGD Proxy Server (ttaauxserv), a different vulnerability than CVE-2014-2472, CVE-2014-2474, and CVE-2014-6459.
