CVE-2018-10999 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in Exiv2 0.26. The Exiv2::Internal::PngChunk::parseTXTChunk function has a heap-based buffer over-read.
CVE-2018-10998 4 Canonical, Debian, Exiv2 and 1 more 6 Ubuntu Linux, Debian Linux, Exiv2 and 3 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
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.
CVE-2018-10963 3 Canonical, Debian, Libtiff 3 Ubuntu Linux, Debian Linux, Libtiff 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
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.
CVE-2018-10958 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
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.
CVE-2018-10938 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 7.1 HIGH 5.9 MEDIUM
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.
CVE-2018-10933 6 Canonical, Debian, Libssh and 3 more 9 Ubuntu Linux, Debian Linux, Libssh and 6 more 2024-11-21 6.4 MEDIUM 9.1 CRITICAL
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.
CVE-2018-10925 3 Canonical, Debian, Postgresql 3 Ubuntu Linux, Debian Linux, Postgresql 2024-11-21 5.5 MEDIUM 8.1 HIGH
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.
CVE-2018-10919 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2024-11-21 4.0 MEDIUM 4.3 MEDIUM
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.
CVE-2018-10918 2 Canonical, Samba 2 Ubuntu Linux, Samba 2024-11-21 4.0 MEDIUM 5.2 MEDIUM
A null pointer dereference flaw was found in the way samba checked database outputs from the LDB database layer. An authenticated attacker could use this flaw to crash a samba server in an Active Directory Domain Controller configuration. Samba versions before 4.7.9 and 4.8.4 are vulnerable.
CVE-2018-10916 3 Canonical, Lftp Project, Opensuse 3 Ubuntu Linux, Lftp, Leap 2024-11-21 7.8 HIGH 5.3 MEDIUM
It has been discovered that lftp up to and including version 4.8.3 does not properly sanitize remote file names, leading to a loss of integrity on the local system when reverse mirroring is used. A remote attacker may trick a user to use reverse mirroring on an attacker controlled FTP server, resulting in the removal of all files in the current working directory of the victim's system.
CVE-2018-10915 4 Canonical, Debian, Postgresql and 1 more 9 Ubuntu Linux, Debian Linux, Postgresql and 6 more 2024-11-21 6.0 MEDIUM 8.5 HIGH
A vulnerability was found in libpq, the default PostgreSQL client library where libpq failed to properly reset its internal state between connections. If an affected version of libpq was used with "host" or "hostaddr" connection parameters from untrusted input, attackers could bypass client-side connection security features, obtain access to higher privileged connections or potentially cause other impact through SQL injection, by causing the PQescape() functions to malfunction. Postgresql versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 are affected.
CVE-2018-10910 2 Bluez, Canonical 2 Bluez, Ubuntu Linux 2024-11-21 2.1 LOW 4.5 MEDIUM
A bug in Bluez may allow for the Bluetooth Discoverable state being set to on when no Bluetooth agent is registered with the system. This situation could lead to the unauthorized pairing of certain Bluetooth devices without any form of authentication. Versions before bluez 5.51 are vulnerable.
CVE-2018-10903 3 Canonical, Cryptography, Redhat 3 Ubuntu Linux, Python-cryptography, Openstack 2024-11-21 5.0 MEDIUM 7.5 HIGH
A flaw was found in python-cryptography versions between >=1.9.0 and <2.3. The finalize_with_tag API did not enforce a minimum tag length. If a user did not validate the input length prior to passing it to finalize_with_tag an attacker could craft an invalid payload with a shortened tag (e.g. 1 byte) such that they would have a 1 in 256 chance of passing the MAC check. GCM tag forgeries can cause key leakage.
CVE-2018-10902 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.
CVE-2018-10883 4 Canonical, Debian, Linux and 1 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2024-11-21 4.9 MEDIUM 4.8 MEDIUM
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bounds write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image.
CVE-2018-10882 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 4.9 MEDIUM 4.8 MEDIUM
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound write in in fs/jbd2/transaction.c code, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image.
CVE-2018-10881 4 Canonical, Debian, Linux and 1 more 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more 2024-11-21 4.9 MEDIUM 4.2 MEDIUM
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image.
CVE-2018-10880 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 7.1 HIGH 5.5 MEDIUM
Linux kernel is vulnerable to a stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could use this to cause a system crash and a denial of service.
CVE-2018-10879 4 Canonical, Debian, Linux and 1 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2024-11-21 6.1 MEDIUM 4.2 MEDIUM
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact may occur by renaming a file in a crafted ext4 filesystem image.
CVE-2018-10878 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2024-11-21 6.1 MEDIUM 7.8 HIGH
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bounds write and a denial of service or unspecified other impact is possible by mounting and operating a crafted ext4 filesystem image.
