Redhat » Enterprise Linux Server : Security Vulnerabilities, CVEs, Published In 2019

Gnome Pango 1.42 and later is affected by: Buffer Overflow. The impact is: The heap based buffer overflow can be used to get code execution. The component is: function name: pango_log2vis_get_embedding_levels, assignment of nchars and the loop condition. The attack vector is: Bug can be used when application pass invalid utf-8 strings to functions like pango_itemize.

libarchive version commit 5a98dcf8a86364b3c2c469c85b93647dfb139961 onwards (version v2.8.0 onwards) contains a CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in ISO9660 parser, archive_read_support_format_iso9660.c, read_CE()/parse_rockridge() that can result in DoS by infinite loop. This attack appears to be exploitable via the victim opening a specially crafted ISO9660 file.

libarchive version commit bf9aec176c6748f0ee7a678c5f9f9555b9a757c1 onwards (release v3.0.2 onwards) contains a CWE-125: Out-of-bounds Read vulnerability in 7zip decompression, archive_read_support_format_7zip.c, header_bytes() that can result in a crash (denial of service). This attack appears to be exploitable via the victim opening a specially crafted 7zip file.

multiSelect in select.c in SQLite 3.30.1 mishandles certain errors during parsing, as demonstrated by errors from sqlite3WindowRewrite() calls. NOTE: this vulnerability exists because of an incomplete fix for CVE-2019-19880.

zipfileUpdate in ext/misc/zipfile.c in SQLite 3.30.1 mishandles a NULL pathname during an update of a ZIP archive.

flattenSubquery in select.c in SQLite 3.30.1 mishandles certain uses of SELECT DISTINCT involving a LEFT JOIN in which the right-hand side is a view. This can cause a NULL pointer dereference (or incorrect results).

exprListAppendList in window.c in SQLite 3.30.1 allows attackers to trigger an invalid pointer dereference because constant integer values in ORDER BY clauses of window definitions are mishandled.

From Eclipse OpenJ9 0.15 to 0.16, access to diagnostic operations such as causing a GC or creating a diagnostic file are permitted without any privilege checks.

Go before 1.12.11 and 1.3.x before 1.13.2 can panic upon an attempt to process network traffic containing an invalid DSA public key. There are several attack scenarios, such as traffic from a client to a server that verifies client certificates.

base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21.

A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.

A flaw was found in the "Leaf and Chain" OCSP policy implementation in JSS' CryptoManager versions after 4.4.6, 4.5.3, 4.6.0, where it implicitly trusted the root certificate of a certificate chain. Applications using this policy may not properly verify the chain and could be vulnerable to attacks such as Man in the Middle.

An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system.

There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.

A flaw was found in ghostscript, versions 9.x before 9.50, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

In KDE Frameworks KConfig before 5.61.0, malicious desktop files and configuration files lead to code execution with minimal user interaction. This relates to libKF5ConfigCore.so, and the mishandling of .desktop and .directory files, as demonstrated by a shell command on an Icon line in a .desktop file.

In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u \#$((0xffffffff))" command.

Type confusion in JavaScript in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

Insufficient policy enforcement in payments in Google Chrome prior to 79.0.3945.79 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page.

Insufficient policy enforcement in downloads in Google Chrome on Windows prior to 79.0.3945.79 allowed a local attacker to spoof downloaded files via local code.

Incorrect security UI in Omnibox in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to perform domain spoofing via IDN homographs via a crafted domain name.

Incorrect security UI in interstitials in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to perform domain spoofing via a crafted HTML page.

Insufficient policy enforcement in navigation in Google Chrome on Android prior to 79.0.3945.79 allowed a remote attacker to bypass navigation restrictions via a crafted HTML page.

Incorrect security UI in Omnibox in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to perform domain spoofing via IDN homographs via a crafted domain name.

Incorrect security UI in printing in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to perform domain spoofing via a crafted HTML page.
