A buffer overflow vulnerability in the dhcp6 client of systemd allows a malicious dhcp6 server to overwrite heap memory in systemd-networkd. Affected releases are systemd: versions up to and including 239.
A vulnerability in unitdeserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. Affected releases are systemd versions up to and including 239.
A race condition in chownone() of systemd allows an attacker to cause systemd to set arbitrary permissions on arbitrary files. Affected releases are systemd versions up to and including 239.
A flaw was found in systemd-journald. A stack buffer overflow when passing several MB of arguments to a program calling syslog function. This can lead to a denial of service attack or arbitrary code execution in some cases.
A flaw was found in systemd-journald. An uncontrolled alloca() by writing a crafted message to /run/systemd/journal/socket that results in a stack buffer overflow. This can lead to a denial of service attack or arbitrary code execution in some cases.
A flaw was found in systemd-journald. An out-of-bounds read when parsing a crafted syslog message that could lead to information disclosure.
A possible QBpmHandler segmentation fault on malformed BMP file. A crafted filed could cause the application to crash.

In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the ASN.1 BER and related dissectors could crash. This was addressed in epan/dissectors/packet-ber.c by preventing a buffer overflow associated with excessive digits in time values.
In AdvanceCOMP 2.1, pngcompress in pngex.cc in advpng has an integer overflow upon encountering an invalid PNG size, which results in an attempted memcpy to write into a buffer that is too small. (There is also a heap-based buffer over-read.)

ImageMagick is vulnerable to a denial of service, caused by a memory leak in WriteDIBImage in coders/dib.c. By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.
ImageMagick is vulnerable to a denial of service, caused by memory leaks in WritePDFImage in coders/pdf.c. By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.
In ImageMagick before 7.0.8-25, a memory leak exists in WritePSDChannel in coders/psd.c.
In ImageMagick before 7.0.8-25, a memory leak exists in ReadSIXELImage in coders/sixel.c.
ImageMagick could allow a remote attacker to obtain sensitive information, caused by memory leaks in DecodeImage in coders/pcd.c. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to obtain sensitive information.
An issue was discovered in sd-bus in systemd 239. busprocessobject() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic).
embed/ephy-web-view.c in GNOME Web (aka Epiphany) through 3.31.4 allows address bar spoofing because a page load triggered by JavaScript leads to updating an address as if it were triggered by a safer visit type (e.g., VISITLINK, VISITTYPED, VISITBOOKMARK, or VISITHOMEPAGE).
Upstream issue: https://gitlab.gnome.org/GNOME/epiphany/issues/532
An off-by-one error was found in spice when accessing arrays. A malicious guest user can use this for a host denial of service.

An issue was discovered in LibVNCServer before 0.9.13. libvncserver/wsdecode.c can lead to a crash because of unaligned accesses in hybiReadAndDecode.
An integer overflow in whoopsie before versions 0.2.52.5ubuntu0.1, 0.2.62ubuntu0.1, 0.2.64ubuntu0.1, 0.2.66, results in an out-of-bounds write to a heap allocated buffer when processing large crash dumps. This results in a crash or possible code-execution in the context of the whoopsie process.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the DCERPC SPOOLSS dissector could crash. This was addressed in epan/dissectors/packet-dcerpc-spoolss.c by adding a boundary check.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the LDSS dissector could crash. This was addressed in epan/dissectors/packet-ldss.c by handling file digests properly.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the SRVLOC dissector could crash. This was addressed in epan/dissectors/packet-srvloc.c by preventing a heap-based buffer under-read.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the GSS-API dissector could crash. This was addressed in epan/dissectors/packet-gssapi.c by ensuring that a valid dissector is called.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the DOF dissector could crash. This was addressed in epan/dissectors/packet-dof.c by properly handling generated IID and OID bytes.
