An issue was discovered in SDDM through 0.17.0. If configured with ReuseSession=true, the password is not checked for users with an already existing session. Any user with access to the system D-Bus can therefore unlock any graphical session. This is related to daemon/Display.cpp and helper/backend/PamBackend.cpp.

wireshark: ISMP dissector crash (wnpa-sec-2018-35)

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the ISMP dissector could crash. This was addressed in epan/dissectors/packet-ismp.c by validating the IPX address length to avoid a buffer over-read.

wireshark: ASN.1 BER and related dissectors crash (wnpa-sec-2018-37)

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the ASN.1 BER dissector could crash. This was addressed in epan/dissectors/packet-ber.c by ensuring that length values do not exceed the maximum signed integer.

wireshark: BGP dissector large loop (wnpa-sec-2018-34)

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the BGP protocol dissector could go into a large loop. This was addressed in epan/dissectors/packet-bgp.c by validating Path Attribute lengths.

wireshark: DICOM dissector infinite loop (wnpa-sec-2018-39)

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the DICOM dissector could go into a large or infinite loop. This was addressed in epan/dissectors/packet-dcm.c by preventing an offset overflow.

wireshark: Multiple dissectors could crash (wnpa-sec-2018-36)

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, dissectors that support zlib decompression could crash. This was addressed in epan/tvbuff_zlib.c by rejecting negative lengths to avoid a buffer over-read.

wireshark: MMSE dissector infinite loop (wnpa-sec-2018-38)

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the MMSE dissector could go into an infinite loop. This was addressed in epan/proto.c by adding offset and length validation.

exiv2: buffer overflow in samples/geotag.cpp

samples/geotag.cpp in the example code of Exiv2 0.26 misuses the realpath function on POSIX platforms (other than Apple platforms) where glibc is not used, possibly leading to a buffer overflow.

The CHECK macro in mrbgems/mruby-sprintf/src/sprintf.c in mruby 1.4.1 contains a signed integer overflow, possibly leading to out-of-bounds memory access because the mrb_str_resize function in string.c does not check for a negative length.

TP-Link WR840N devices allow remote attackers to cause a denial of service (connectivity loss) via a series of packets with random MAC addresses.

h2: Information Exposure due to insecure handling of permissions in the backup

An issue was discovered in H2 1.4.197. Insecure handling of permissions in the backup function allows attackers to read sensitive files (outside of their permissions) via a symlink to a fake database file.

manager/editor/upload.php in joyplus-cms 1.6.0 allows arbitrary file upload because detection of a prohibited file extension simply sets the $errm value, and does not otherwise alter the flow of control. Consequently, one can upload and execute a .php file, a similar issue to CVE-2018-8766.

TeamViewer through 13.1.1548 stores a password in Unicode format within TeamViewer.exe process memory between "[00 88] and "[00 00 00]" delimiters, which might make it easier for attackers to obtain sensitive information by leveraging an unattended workstation on which TeamViewer has disconnected but remains running.

An issue was discovered in Clementine Music Player 1.3.1. Clementine.exe is vulnerable to a user mode write access violation due to a NULL pointer dereference in the Init call in the MoodbarPipeline::NewPadCallback function in moodbar/moodbarpipeline.cpp. The vulnerability is triggered when the user opens a malformed mp3 file.

An issue was discovered in XiaoCms X1 v20140305. There is a CSRF vulnerability to change the administrator account password via admin/index.php?c=index&a=my.

In HTSlib 1.8, a race condition in cram/cram_io.c might allow local users to overwrite arbitrary files via a symlink attack.

Brynamics "Online Trade - Online trading and cryptocurrency investment system" allows remote attackers to obtain sensitive information via a direct request for /dashboard/addplan, /dashboard/paywithcard/charge, /dashboard/withdrawal, or /privacy&terms, as demonstrated by reading database username, database password, database_name, and IP address fields, related to CVE-2018-12908.

The installer for the Alcatel OSPREY3_MINI Modem component on EE EE40VB 4G mobile broadband modems with firmware before EE40_00_02.00_45 sets weak permissions (Everyone:Full Control) for the "Web Connecton\EE40" and "Web Connecton\EE40\BackgroundService" directories, which allows local users to gain privileges, as demonstrated by inserting a Trojan horse ServiceManager.exe file into the "Web Connecton\EE40\BackgroundService" directory.

In MP4v2 2.0.0, there is an integer overflow (with resultant memory corruption) when resizing MP4Array for the ftyp atom in mp4array.h.

In MP4v2 2.0.0, there is an integer underflow (with resultant memory corruption) when parsing MP4Atom in mp4atom.cpp.
