irssi: Unchecked input in unformat_24bit_color() can lead to crash

The unformat_24bit_color function in the format parsing code in Irssi before 0.8.20, when compiled with true-color enabled, allows remote attackers to cause a denial of service (heap corruption and crash) via an incomplete 24bit color code.

irssi: String length not validated in format_send_to_gui() causing crash

The format_send_to_gui function in the format parsing code in Irssi before 0.8.20 allows remote attackers to cause a denial of service (heap corruption and crash) via vectors involving the length of a string.

glibc: Stack-overflow in glibc swscanf

The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during a risk-management decision for use of the alloca function, which might allow context-dependent attackers to cause a denial of service (segmentation violation) or overwrite memory locations beyond the stack boundary via a long line containing wide characters that are improperly handled in a wscanf call.

glibc: heap buffer overflow in glibc swscanf

The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during memory allocation, which allows context-dependent attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a long line containing wide characters that are improperly handled in a wscanf call.

kernel: net: DoS due to routing packets to too many different dsts/too fast

The IPv4 implementation in the Linux kernel before 3.18.8 does not properly consider the length of the Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allows remote attackers to cause a denial of service (memory consumption or system crash) via a flood of packets.

kernel: net: slab corruption from use after free on INIT collisions

Use-after-free vulnerability in the sctp_assoc_update function in net/sctp/associola.c in the Linux kernel before 3.18.8 allows remote attackers to cause a denial of service (slab corruption and panic) or possibly have unspecified other impact by triggering an INIT collision that leads to improper handling of shared-key data.

chromium-browser: unspecified vulnerability in Google V8

Multiple unspecified vulnerabilities in Google V8 before 3.30.33.15, as used in Google Chrome before 40.0.2214.91, allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

The do_write_pids function in lxcfs.c in LXCFS before 0.12 does not properly check permissions, which allows local users to gain privileges by writing a pid to the tasks file.

systemd: Assertion failure when PID 1 receives a zero-length message over notify socket

The manager_invoke_notify_message function in systemd 231 and earlier allows local users to cause a denial of service (assertion failure and PID 1 hang) via a zero-length message received over a notify socket.

kernel: media: use-after-free in [tuner-xc2028] media driver

The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure.

LXCFS before 0.12 does not properly enforce directory escapes, which might allow local users to gain privileges by (1) querying or (2) updating a cgroup.

kernel_crashdump in Apport before 2.19 allows local users to cause a denial of service (disk consumption) or possibly gain privileges via a (1) symlink or (2) hard link attack on /var/crash/vmcore.log.

python-django: user with hardcoded password created when running tests on Oracle

Django 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3 use a hardcoded password for a temporary database user created when running tests with an Oracle database, which makes it easier for remote attackers to obtain access to the database server by leveraging failure to manually specify a password in the database settings TEST dictionary.

python-django: DNS rebinding vulnerability when 'DEBUG=True'

Django before 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3, when settings.DEBUG is True, allow remote attackers to conduct DNS rebinding attacks by leveraging failure to validate the HTTP Host header against settings.ALLOWED_HOSTS.

Simple Streams (simplestreams) does not properly verify the GPG signatures of disk image files, which allows remote mirror servers to spoof disk images and have unspecified other impact via a 403 (aka Forbidden) response.

lxc-start in lxc before 1.0.8 and 1.1.x before 1.1.4 allows local container administrators to escape AppArmor confinement via a symlink attack on a (1) mount target or (2) bind mount source.

unattended-upgrades before 0.86.1 does not properly authenticate packages when the (1) force-confold or (2) force-confnew dpkg options are enabled in the DPkg::Options::* apt configuration, which allows remote man-in-the-middle attackers to upload and execute arbitrary packages via unspecified vectors.

The overlayfs implementation in the linux (aka Linux kernel) package before 3.19.0-21.21 in Ubuntu through 15.04 does not properly check permissions for file creation in the upper filesystem directory, which allows local users to obtain root access by leveraging a configuration in which overlayfs is permitted in an arbitrary mount namespace.

Directory traversal vulnerability in the Ubuntu network-manager package for Ubuntu (vivid) before 0.9.10.0-4ubuntu15.1, Ubuntu 14.10 before 0.9.8.8-0ubuntu28.1, and Ubuntu 14.04 LTS before 0.9.8.8-0ubuntu7.1 allows local users to change the modem device configuration or read arbitrary files via a .. (dot dot) in the file name in a request to read modem device contexts (com.canonical.NMOfono.ReadImsiContexts).

Use-after-free vulnerability in the file picker implementation in Oxide before 1.6.5 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted webpage.
