libjpeg: Segmentation fault in get_text_gray_row function in rdppm.c

An issue was discovered in libjpeg 9a. The get_text_gray_row function in rdppm.c allows remote attackers to cause a denial of service (Segmentation fault) via a crafted file.

exiv2: heap-based buffer over-read in parseTXTChunk function

An issue was discovered in Exiv2 0.26. The Exiv2::Internal::PngChunk::parseTXTChunk function has a heap-based buffer over-read.

exiv2: SIGABRT by triggering an incorrect Safe::add call

An issue was discovered in Exiv2 0.26. readMetadata in jp2image.cpp allows remote attackers to cause a denial of service (SIGABRT) by triggering an incorrect Safe::add call.

SchedMD Slurm before 17.02.11 and 17.1x.x before 17.11.7 mishandles user names (aka user_name fields) and group ids (aka gid fields).

xen: x86 vHPET interrupt injection errors (XSA-261)

An issue was discovered in Xen through 4.10.x allowing x86 HVM guest OS users to cause a denial of service (unexpectedly high interrupt number, array overrun, and hypervisor crash) or possibly gain hypervisor privileges by setting up an HPET timer to deliver interrupts in IO-APIC mode, aka vHPET interrupt injection.

xen: qemu may drive Xen into unbounded loop (XSA-262)

An issue was discovered in Xen through 4.10.x allowing x86 HVM guest OS users to cause a denial of service (host OS infinite loop) in situations where a QEMU device model attempts to make invalid transitions between states of a request.

libtiff: reachable assertion in TIFFWriteDirectorySec function in tif_dirwrite.c

The TIFFWriteDirectorySec() function in tif_dirwrite.c in LibTIFF through 4.0.9 allows remote attackers to cause a denial of service (assertion failure and application crash) via a crafted file, a different vulnerability than CVE-2017-13726.

exiv2: SIGABRT caused by memory allocation in types.cpp:Exiv2::Internal::PngChunk::zlibUncompress()

In types.cpp in Exiv2 0.26, a large size value may lead to a SIGABRT during an attempt at memory allocation for an Exiv2::Internal::PngChunk::zlibUncompress call.

kernel: incorrect memory bounds check in drivers/cdrom/cdrom.c

The cdrom_ioctl_media_changed function in drivers/cdrom/cdrom.c in the Linux kernel before 4.16.6 allows local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory.

kernel: infinite loop in net/ipv4/cipso_ipv4.c:cipso_v4_optptr() allows for DoS

A flaw was found in the Linux kernel present since v4.0-rc1 and through v4.13-rc4. A crafted network packet sent remotely by an attacker may force the kernel to enter an infinite loop in the cipso_v4_optptr() function in net/ipv4/cipso_ipv4.c leading to a denial-of-service. A certain non-default configuration of LSM (Linux Security Module) and NetLabel should be set up on a system before an attacker could leverage this flaw.

libssh: Authentication Bypass due to improper message callbacks implementation

A vulnerability was found in libssh's server-side state machine before versions 0.7.6 and 0.8.4. A malicious client could create channels without first performing authentication, resulting in unauthorized access.

glusterfs: Files can be renamed outside volume

A flaw was found in RPC request using gfs3_rename_req in glusterfs server. An authenticated attacker could use this flaw to write to a destination outside the gluster volume.

glusterfs: Arbitrary file creation on storage server allows for execution of arbitrary code

A flaw was found in RPC request using gfs2_create_req in glusterfs server. An authenticated attacker could use this flaw to create arbitrary files and execute arbitrary code on glusterfs server nodes.

glusterfs: Improper resolution of symlinks allows for privilege escalation

A flaw was found in RPC request using gfs3_symlink_req in glusterfs server which allows symlink destinations to point to file paths outside of the gluster volume. An authenticated attacker could use this flaw to create arbitrary symlinks pointing anywhere on the server and execute arbitrary code on glusterfs server nodes.

glusterfs: File status information leak and denial of service

A flaw was found in RPC request using gfs3_lookup_req in glusterfs server. An authenticated attacker could use this flaw to leak information and execute remote denial of service by crashing gluster brick process.

glusterfs: Device files can be created in arbitrary locations

A flaw was found in RPC request using gfs3_mknod_req supported by glusterfs server. An authenticated attacker could use this flaw to write files to an arbitrary location via path traversal and execute arbitrary code on a glusterfs server node.

postgresql: Missing authorization and memory disclosure in INSERT ... ON CONFLICT DO UPDATE statements

It was discovered that PostgreSQL versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 failed to properly check authorization on certain statements involved with "INSERT ... ON CONFLICT DO UPDATE". An attacker with "CREATE TABLE" privileges could exploit this to read arbitrary bytes server memory. If the attacker also had certain "INSERT" and limited "UPDATE" privileges to a particular table, they could exploit this to update other columns in the same table.

glusterfs: I/O to arbitrary devices on storage server

It was found that the "mknod" call derived from mknod(2) can create files pointing to devices on a glusterfs server node. An authenticated attacker could use this to create an arbitrary device and read data from any device attached to the glusterfs server node.

samba: Confidential attribute disclosure via substring search

The Samba Active Directory LDAP server was vulnerable to an information disclosure flaw because of missing access control checks. An authenticated attacker could use this flaw to extract confidential attribute values using LDAP search expressions. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable.
