OpenDMARC through 1.3.2 and 1.4.x through 1.4.0-Beta1 is prone to a signature-bypass vulnerability with multiple From: addresses, which might affect applications that consider a domain name to be relevant to the origin of an e-mail message.

golang: HTTP/1.1 headers with a space before the colon leads to filter bypass or request smuggling

Go before 1.12.10 and 1.13.x before 1.13.1 allow HTTP Request Smuggling.

process_http_response in OpenConnect before 8.05 has a Buffer Overflow when a malicious server uses HTTP chunked encoding with crafted chunk sizes.

Dino before 2019-09-10 does not properly check the source of an MAM message in module/xep/0313_message_archive_management.vala.

Dino before 2019-09-10 does not check roster push authorization in module/roster/module.vala.

Dino before 2019-09-10 does not properly check the source of a carbons message in module/xep/0280_message_carbons.vala.

kernel: null-pointer dereference in drivers/net/wireless/marvell/libertas/if_sdio.c

drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.

sysstat: memory corruption due to an integer overflow in remap_struct in sa_common.c

sysstat before 12.1.6 has memory corruption due to an Integer Overflow in remap_struct() in sa_common.c.

oniguruma: Stack exhaustion in regcomp.c because of recursion in regparse.c

Oniguruma before 6.9.3 allows Stack Exhaustion in regcomp.c because of recursion in regparse.c.

BIRD Internet Routing Daemon 1.6.x through 1.6.7 and 2.x through 2.0.5 has a stack-based buffer overflow. The BGP daemon's support for RFC 8203 administrative shutdown communication messages included an incorrect logical expression when checking the validity of an input message. Sending a shutdown communication with a sufficient message length causes a four-byte overflow to occur while processing the message, where two of the overflow bytes are attacker-controlled and two are fixed.

opensc: Out-of-bounds access of an ASN.1 Octet string in asn1_decode_entry in libopensc/asn1.c

OpenSC before 0.20.0-rc1 has an out-of-bounds access of an ASN.1 Octet string in asn1_decode_entry in libopensc/asn1.c.

opensc: Out-of-bounds access of an ASN.1 Bitstring in decode_bit_string in libopensc/asn1.c

OpenSC before 0.20.0-rc1 has an out-of-bounds access of an ASN.1 Bitstring in decode_bit_string in libopensc/asn1.c.

systemd: systemd-resolved allows unprivileged users to configure DNS

In systemd 240, bus_open_system_watch_bind_with_description in shared/bus-util.c (as used by systemd-resolved to connect to the system D-Bus instance), calls sd_bus_set_trusted, which disables access controls for incoming D-Bus messages. An unprivileged user can exploit this by executing D-Bus methods that should be restricted to privileged users, in order to change the system's DNS resolver settings.

rubygem-loofah: XXS when a crafted SVG element is republished

In the Loofah gem for Ruby through v2.3.0 unsanitized JavaScript may occur in sanitized output when a crafted SVG element is republished.

kernel: denial of service in in xfs_setattr_nonsize in fs/xfs/xfs_iops.c

An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS.

GNU Libextractor through 1.9 has a heap-based buffer over-read in the function EXTRACTOR_dvi_extract_method in plugins/dvi_extractor.c.

Roundcube Webmail through 1.3.9 mishandles Punycode xn-- domain names, leading to homograph attacks.

AdPlug 2.3.1 has a double free in the Cu6mPlayer class in u6m.h.

DjVuLibre 3.5.27 allows attackers to cause a denial-of-service attack (application crash via an out-of-bounds read) by crafting a corrupted JB2 image file that is mishandled in JB2Dict::JB2Codec::get_direct_context in libdjvu/JB2Image.h because of a missing zero-bytes check in libdjvu/GBitmap.h.

In DjVuLibre 3.5.27, the sorting functionality (aka GArrayTemplate<TYPE>::sort) allows attackers to cause a denial-of-service (application crash due to an Uncontrolled Recursion) by crafting a PBM image file that is mishandled in libdjvu/GContainer.h.
