chromium-browser: Out of bounds read in Blink

A use after free in Blink in Google Chrome prior to 69.0.3497.81 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

chromium-browser: Out of bounds write in V8

A Javascript reentrancy issues that caused a use-after-free in V8 in Google Chrome prior to 69.0.3497.81 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page.

elfutils: Heap-based buffer over-read in libdw/dwarf_getaranges.c:dwarf_getaranges() via crafted file

dwarf_getaranges in dwarf_getaranges.c in libdw in elfutils before 2018-08-18 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted file.

wireshark: Bluetooth AVDTP dissector crash

In Wireshark 2.6.0 to 2.6.2, 2.4.0 to 2.4.8, and 2.2.0 to 2.2.16, the Bluetooth AVDTP dissector could crash. This was addressed in epan/dissectors/packet-btavdtp.c by properly initializing a data structure.

wireshark: Radiotap dissector crash

In Wireshark 2.6.0 to 2.6.2, 2.4.0 to 2.4.8, and 2.2.0 to 2.2.16, the Radiotap dissector could crash. This was addressed in epan/dissectors/packet-ieee80211-radiotap-iter.c by validating iterator operations.

wireshark: Bluetooth Attribute Protocol dissector crash

In Wireshark 2.6.0 to 2.6.2, 2.4.0 to 2.4.8, and 2.2.0 to 2.2.16, the Bluetooth Attribute Protocol dissector could crash. This was addressed in epan/dissectors/packet-btatt.c by verifying that a dissector for a specific UUID exists.

ghostscript: Uninitialized memory access in the aesdecode operator (699665)

In Artifex Ghostscript 9.23 before 2018-08-24, attackers able to supply crafted PostScript could use uninitialized memory access in the aesdecode operator to crash the interpreter or potentially execute code.

ghostscript: LockDistillerParams type confusion (699656)

In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the LockDistillerParams parameter to crash the interpreter or execute code.

ghostscript: shading_param incomplete type checking (699660)

In Artifex Ghostscript 9.23 before 2018-08-24, a type confusion using the .shfill operator could be used by attackers able to supply crafted PostScript files to crash the interpreter or potentially execute code.

ghostscript: .tempfile file permission issues (699657)

In Artifex Ghostscript 9.23 before 2018-08-23, attackers are able to supply malicious PostScript files to bypass .tempfile restrictions and write files.

The flv_write_packet function in libavformat/flvenc.c in FFmpeg through 2.8 does not check for an empty audio packet, leading to an assertion failure.

The recv_msg_userauth_request function in svr-auth.c in Dropbear through 2018.76 is prone to a user enumeration vulnerability because username validity affects how fields in SSH_MSG_USERAUTH messages are handled, a similar issue to CVE-2018-15473 in an unrelated codebase.

kernel: Mishandling of indirect calls weakens Spectre mitigation for paravirtual guests

arch/x86/kernel/paravirt.c in the Linux kernel before 4.18.1 mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtual guests.

evolution: specially crafted email leading to OpenPGP signatures being spoofed for arbitrary messages

GNOME Evolution through 3.28.2 is prone to OpenPGP signatures being spoofed for arbitrary messages using a specially crafted email that contains a valid signature from the entity to be impersonated as an attachment.

Kernel: hw: cpu: userspace-userspace spectreRSB attack

The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c in the Linux kernel before 4.18.1 does not always fill RSB upon a context switch, which makes it easier for attackers to conduct userspace-userspace spectreRSB attacks.

qt5-qtbase: Double free in QXmlStreamReader

QXmlStream in Qt 5.x before 5.11.3 has a double-free or corruption during parsing of a specially crafted illegal XML document.

libgit2: out-of-bounds reads when processing smart-protocol ng packets

In ng_pkt in transports/smart_pkt.c in libgit2 before 0.26.6 and 0.27.x before 0.27.4, a remote attacker can send a crafted smart-protocol "ng" packet that lacks a '\0' byte to trigger an out-of-bounds read that leads to DoS.

dojo: Cross-site scripting (XSS) due to unescaped strings when editing rows in dojox/Grid/DataGrid

In Dojo Toolkit before 1.14, there is unescaped string injection in dojox/Grid/DataGrid.

xen: Use of v2 grant tables may cause crash on ARM (XSA-268)

An issue was discovered in Xen through 4.11.x. ARM never properly implemented grant table v2, either in the hypervisor or in Linux. Unfortunately, an ARM guest can still request v2 grant tables; they will simply not be properly set up, resulting in subsequent grant-related hypercalls hitting BUG() checks. An unprivileged guest can cause a BUG() check in the hypervisor, resulting in a denial-of-service (crash).

libtiff: Heap-based buffer overflow in ChopUpSingleUncompressedStrip in tif_dirread.c

ChopUpSingleUncompressedStrip in tif_dirread.c in LibTIFF 4.0.9 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted TIFF file, as demonstrated by tiff2pdf.
