The (1) HTTP and (2) FTP coders in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allow remote attackers to conduct server-side request forgery (SSRF) attacks via a crafted image.

The EPHEMERAL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to delete arbitrary files via a crafted image.

Oracle Java SE 6u105, 7u91 and 8u65 fixes an unspecified vulnerability in the Deployment component (CVE-2015-4902). Upstream has CVSSv2 scored this issue as: 5.0/AV:N/AC:L/Au:N/C:N/I:P/A:N

As per the upstream advisory:

By sending an invalid DTLS handshake to an OpenSSL DTLS client, the code can be made to recurse, eventually crashing in a DoS attack.

Only applications using OpenSSL as a DTLS client are affected.

OpenSSL 0.9.8 DTLS users should upgrade to 0.9.8za OpenSSL 1.0.0 DTLS users should upgrade to 1.0.0m. OpenSSL 1.0.1 DTLS users should upgrade to 1.0.1h. .

The dossl3write function in s3pkt.c in OpenSSL 1.x through 1.0.1g, when SSLMODERELEASEBUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors that trigger an alert condition.

As per the upstream advisory:

OpenSSL TLS clients enabling anonymous ECDH ciphersuites are subject to a denial of service attack.

OpenSSL 1.0.0 users should upgrade to 1.0.0m. OpenSSL 1.0.1 users should upgrade to 1.0.1h.

Race condition in the ssl3readbytes function in s3pkt.c in OpenSSL through 1.0.1g, when SSLMODERELEASEBUFFERS is enabled, allows remote attackers to inject data across sessions or cause a denial of service (use-after-free and parsing error) via an SSL connection in a multithreaded environment.

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm access, as demonstrated by PRSETTSC prctl calls within a modified copy of QEMU.

It was reported [1] that iptables can allow protocols that do not have a protocol handler kernel module loaded.

Given following iptables ruleset: -P FORWARD DROP -A FORWARD -m sctp --dport 9 -j ACCEPT -A FORWARD -p tcp --dport 80 -j ACCEPT -A FORWARD -p tcp -m conntrack -m state ESTABLISHED,RELATED -j ACCEPT

One would assume that this allows SCTP on port 9 and TCP on port 80. Unfortunately, if the SCTP conntrack module is not loaded, this allows all SCTP communication to pass through, i.e. -p sctp -j ACCEPT

A local kernel crash on invalid USB device requiring the visor driver was reported. The treoattach() function of the [visor] driver, which is called during the driver initialization process, was dereferencing the bulk-in and interrupt-in urbs without first making sure they had been allocated by core. Due to an incomplete sanity check, the visor driver tries to dereference null-pointers, which results in crash.

Vulnerable code:
