elfutils: elflint.c does not validate the number of sections and segments

elflint.c in elfutils 0.168 does not validate the number of sections and the number of segments, which allows remote attackers to cause a denial of service (memory consumption) via a crafted ELF file.

kernel: nfsd: Incorrect handling of long RPC replies

The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c.

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.

qpdf: Infinite loop related to releaseResolved functions

libqpdf.a in QPDF 6.0.0 allows remote attackers to cause a denial of service (infinite recursion and stack consumption) via a crafted PDF document, related to releaseResolved functions, aka qpdf-infiniteloop1.

elfutils: Heap-buffer overflow in the ebl_object_note_type_name function

The ebl_object_note_type_name function in eblobjnotetypename.c in elfutils 0.168 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file.

elfutils: Heap-buffer overflow in the check_group function

The check_group function in elflint.c in elfutils 0.168 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file.

kernel: Out-of-bounds heap access in xfrm

The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel through 4.10.6 does not validate certain size data after an XFRM_MSG_NEWAE update, which allows local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability, as demonstrated during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10 linux-image-* package 4.8.0.41.52.

An issue was discovered in certain Apple products. iOS before 11.2 is affected. Safari before 11.0.2 is affected. iCloud before 7.2 on Windows is affected. iTunes before 12.7.2 on Windows is affected. tvOS before 11.2 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

In LightDM through 1.22.0, a directory traversal issue in debian/guest-account.sh allows local attackers to own arbitrary directory path locations and escalate privileges to root when the guest user logs out.

elfutils: Heap-buffer overflow in the check_symtab_shndx function

The check_symtab_shndx function in elflint.c in elfutils 0.168 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file.

ImageMagick: filling memory during identification of image

coders/tiff.c in ImageMagick allows remote attackers to cause a denial of service (application crash) via vectors related to the "identification of image."

ImageMagick: memory leak in rle file handling

Memory leak in coders/rle.c in ImageMagick allows remote attackers to cause a denial of service (memory consumption) via a crafted rle file.

ImageMagick: crash when parsing resource block

ImageMagick 6.8.9.9 allows remote attackers to cause a denial of service (application crash).

perl-File-Path: rmtree/remove_tree race condition

Race condition in the rmtree and remove_tree functions in the File-Path module before 2.13 for Perl allows attackers to set the mode on arbitrary files via vectors involving directory-permission loosening logic.

An issue was discovered in network-manager-applet (aka network-manager-gnome) in Ubuntu 12.04 LTS, 14.04 LTS, 16.04 LTS, and 16.10. A local attacker could use this issue at the default Ubuntu login screen to access local files and execute arbitrary commands as the lightdm user. The exploitation requires physical access to the locked computer and the Wi-Fi must be turned on. An access point that lets you use a certificate to login is required as well, but it's easy to create one. Then, it's possible to open a nautilus window and browse directories. One also can open some applications such as Firefox, which is useful for downloading malicious binaries.

ImageMagick: crash in png coder

The png coder in ImageMagick allows remote attackers to cause a denial of service (crash).

ImageMagick: incorrect thread limit logic

Logic error in ImageMagick 6.8.9.9 allows remote attackers to cause a denial of service (resource consumption).

An issue was discovered in apng2gif 1.7. There is an integer overflow resulting in a heap-based buffer over-read, related to the load_apng function and the imagesize variable.

ImageMagick: overflow in rle file

Buffer overflow in the ReadRLEImage function in coders/rle.c in ImageMagick 6.8.9.9 allows remote attackers to have unspecified impact.

ImageMagick: crash due to corrupted dib file

The ReadDIBImage function in coders/dib.c in ImageMagick allows remote attackers to cause a denial of service (crash) via a corrupted dib file.
