Qemu: scsi: vmw_pvscsi: infinite loop in pvscsi_log2

hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (infinite loop and CPU consumption) via the message ring page count.

xen: possibly unbounded recursion in grant table code (XSA-226)

Xen allows local OS guest users to cause a denial of service (crash) or possibly obtain sensitive information or gain privileges via vectors involving transitive grants.

xen: grant_table: Race conditions with maptrack free list handling (XSA-228)

Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling.

xen: x86: PV privilege escalation via map_grant_ref (XSA-227)

arch/x86/mm.c in Xen allows local PV guest OS users to gain host OS privileges via vectors related to map_grant_ref.

freetype: heap-based buffer overflow related to the t1_decoder_parse_charstrings

FreeType 2 before 2017-03-24 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1_decoder_parse_charstrings function in psaux/t1decode.c.

WeeChat before 1.7.1 allows a remote crash by sending a filename via DCC to the IRC plugin. This occurs in the irc_ctcp_dcc_filename_without_quotes function during quote removal, with a buffer overflow.

kernel: null pointer dereference in nl80211_set_rekey_data()

A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel through 4.13.3. This function does not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash.

kernel: dvb_usb_core.c interacts incorrectly with the CONFIG_VMAP_STACK option

drivers/media/usb/dvb-usb-v2/dvb_usb_core.c in the Linux kernel 4.9.x and 4.10.x before 4.10.12 interacts incorrectly with the CONFIG_VMAP_STACK option, which allows local users to cause a denial of service (system crash or memory corruption) or possibly have unspecified other impact by leveraging use of more than one virtual page for a DMA scatterlist.

OpenVPN versions before 2.3.3 and 2.4.x before 2.4.4 are vulnerable to a buffer overflow vulnerability when key-method 1 is used, possibly resulting in code execution.

libtiff: Multiple uint32 overflows leading to heap buffer over-read

Integer overflow in the writeBufferToSeparateStrips function in tiffcrop.c in LibTIFF before 4.0.7 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted tif file.

spring-ldap: Authentication with userSearch and STARTTLS allows authentication with arbitrary password

In Pivotal Spring-LDAP versions 1.3.0 - 2.3.1, when connected to some LDAP servers, when no additional attributes are bound, and when using LDAP BindAuthenticator with org.springframework.ldap.core.support.DefaultTlsDirContextAuthenticationStrategy as the authentication strategy, and setting userSearch, authentication is allowed with an arbitrary password when the username is correct. This occurs because some LDAP vendors require an explicit operation for the LDAP bind to take effect.

Qemu: display: cirrus: OOB r/w access issues in bitblt routines

Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation.

ImageMagick: Memory leak in ReadSVGImage

The ReadSVGImage function in svg.c in ImageMagick 7.0.5-4 allows remote attackers to consume an amount of available memory via a crafted file.

ImageMagick: Memory leak in ReadSGIImage

The ReadSGIImage function in sgi.c in ImageMagick 7.0.5-4 allows remote attackers to consume an amount of available memory via a crafted file.

kernel: NFSv3 server does not properly handle payload bounds checking of WRITE requests

The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.

kernel: mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism

The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c.

The MagickMalloc function in magick/memory.c in GraphicsMagick 1.3.25 allows remote attackers to have unspecified impact via a crafted image, which triggers a memory allocation failure and a "file truncation error for corrupt file."

The ReadPCXImage function in coders/pcx.c in GraphicsMagick 1.3.25 allows remote attackers to have unspecified impact via a crafted image, which triggers a memory allocation failure and a "file truncation error for corrupt file."

shadow-utils: Buffer overflow via newusers tool

In shadow before 4.5, the newusers tool could be made to manipulate internal data structures in ways unintended by the authors. Malformed input may lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors. This crosses a privilege boundary in, for example, certain web-hosting environments in which a Control Panel allows an unprivileged user account to create subaccounts.

libsndfile: Heap-based Buffer Overflow in psf_binheader_writef function in common.c

Heap-based Buffer Overflow in the psf_binheader_writef function in common.c in libsndfile through 1.0.28 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
