In Mosquitto before 1.4.12, pattern based ACLs can be bypassed by clients that set their username/client id to '#' or '+'. This allows locally or remotely connected clients to access MQTT topics that they do have the rights to. The same issue may be present in third party authentication/access control plugins for Mosquitto.

httpd: ap_find_token() buffer overread

The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. By maliciously crafting a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value.

wireshark: SLSK dissector long loop (wnpa-sec-2017-19)

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the SLSK dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-slsk.c by adding checks for the remaining length.

wireshark: PacketBB dissector crash (wnpa-sec-2017-18)

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the PacketBB dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-packetbb.c by restricting additions to the protocol tree.

ImageMagick: Memory leak in ReadSGIImage

The ReadSGIImage function in sgi.c in ImageMagick 7.0.5-4 allows remote attackers to consume an amount of available memory via a crafted file.

ImageMagick: Memory leak in ReadSVGImage

The ReadSVGImage function in svg.c in ImageMagick 7.0.5-4 allows remote attackers to consume an amount of available memory via a crafted file.

WeeChat before 1.7.1 allows a remote crash by sending a filename via DCC to the IRC plugin. This occurs in the irc_ctcp_dcc_filename_without_quotes function during quote removal, with a buffer overflow.

Qemu: scsi: vmw_pvscsi: infinite loop in pvscsi_log2

hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (infinite loop and CPU consumption) via the message ring page count.

ImageMagick: Memory leak in the ReadAAIImage function

In ImageMagick 7.0.5-5, the ReadAAIImage function in aai.c allows attackers to cause a denial of service (memory leak) via a crafted file.

ImageMagick: Memory leak in the ReadPCXImage function

In ImageMagick 7.0.5-5, the ReadPCXImage function in pcx.c allows attackers to cause a denial of service (memory leak) via a crafted file.

ImageMagick: Memory leak in the ReadMNGImage function

In ImageMagick 7.0.5-5, the ReadMNGImage function in png.c allows attackers to cause a denial of service (memory leak) via a crafted file.

ImageMagick: Memory leak in the ReadDCMImage function

In ImageMagick 7.0.5-5, the ReadDCMImage function in dcm.c allows attackers to cause a denial of service (memory leak) via a crafted file.

ImageMagick: Memory leak in the ReadEXRImage function

In ImageMagick 7.0.5-5, the ReadEXRImage function in exr.c allows attackers to cause a denial of service (memory leak) via a crafted file.

ImageMagick: Memory leak in the ReadMATImage function

In ImageMagick 7.0.5-5, the ReadMATImage function in mat.c allows attackers to cause a denial of service (memory leak) via a crafted file.

ImageMagick: Memory leak in the ReadSFWImage function

In ImageMagick 7.0.5-5, the ReadSFWImage function in sfw.c allows attackers to cause a denial of service (memory leak) via a crafted file.

git: Escape out of git-shell

git-shell in git before 2.4.12, 2.5.x before 2.5.6, 2.6.x before 2.6.7, 2.7.x before 2.7.5, 2.8.x before 2.8.5, 2.9.x before 2.9.4, 2.10.x before 2.10.3, 2.11.x before 2.11.2, and 2.12.x before 2.12.3 might allow remote authenticated users to gain privileges via a repository name that starts with a - (dash) character.

Debian ftpsync before 20171017 does not use the rsync --safe-links option, which allows remote attackers to conduct directory traversal attacks via a crafted upstream mirror.

The Debian pg_ctlcluster, pg_createcluster, and pg_upgradecluster scripts, as distributed in the Debian postgresql-common package before 181+deb9u1 for PostgreSQL (and other packages related to Debian and Ubuntu), handled symbolic links insecurely, which could result in local denial of service by overwriting arbitrary files.

varnish: Data leak - ‘-sfile’ Stevedore transient objects

vbf_stp_error in bin/varnishd/cache/cache_fetch.c in Varnish HTTP Cache 4.1.x before 4.1.9 and 5.x before 5.2.1 allows remote attackers to obtain sensitive information from process memory because a VFP_GetStorage buffer is larger than intended in certain circumstances involving -sfile Stevedore transient objects.

MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2 has XSS when the $wgShowExceptionDetails setting is false and the browser sends non-standard URL escaping.
