kernel: Invalid pointer dereference in fs/btrfs/relocation.c:__del_reloc_root() when mounting crafted btrfs image

An issue was discovered in the Linux kernel through 4.17.10. There is an invalid pointer dereference in __del_reloc_root() in fs/btrfs/relocation.c when mounting a crafted btrfs image, related to removing reloc rb_trees when reloc control has not been initialized.

libX11: Out of Bounds write in XListExtensions in ListExt.c

An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading to DoS or remote code execution.

libX11: Off-by-one error in XListExtensions in ListExt.c

An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other impact.

libX11: Crash on invalid reply in XListExtensions in ListExt.c

An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed later on, leading to DoS (segmentation fault).

An issue was discovered in Open Ticket Request System (OTRS) 6.0.x through 6.0.9, 5.0.x through 5.0.28, and 4.0.x through 4.0.30. An attacker who is logged into OTRS as an agent may escalate their privileges by accessing a specially crafted URL.

django: Open redirect possibility in CommonMiddleware

django.middleware.common.CommonMiddleware in Django 1.11.x before 1.11.15 and 2.0.x before 2.0.8 has an Open Redirect.

gd: NULL pointer dereference in gdImageClone

gdImageClone in gd.c in libgd 2.1.0-rc2 through 2.2.5 has a NULL pointer dereference allowing attackers to crash an application via a specific function call sequence. Only affects PHP when linked with an external libgd (not bundled).

wpa_supplicant: Unauthenticated EAPOL-Key decryption in wpa_supplicant

An issue was discovered in rsn_supp/wpa.c in wpa_supplicant 2.0 through 2.6. Under certain conditions, the integrity of EAPOL-Key messages is not checked, leading to a decryption oracle. An attacker within range of the Access Point and client can abuse the vulnerability to recover sensitive information.

libjpeg-turbo: heap-based buffer over-read via crafted 8-bit BMP in get_8bit_row in rdbmp.c leads to denial of service

get_8bit_row in rdbmp.c in libjpeg-turbo through 1.5.90 and MozJPEG through 3.3.1 allows attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted 8-bit BMP in which one or more of the color indices is out of range for the number of palette entries.

tcpdump: Buffer over-read in ikev1_n_print() function in print-isakmp.c

The IKEv1 parser in tcpdump before 4.9.3 has a buffer over-read in print-isakmp.c:ikev1_n_print().

tcpdump: Buffer over-read in print-icmp6.c

The Rx parser in tcpdump before 4.9.3 has a buffer over-read in print-rx.c:rx_cache_find() and rx_cache_insert().

tcpdump: Buffer over-read in lmp_print_data_link_subobjs() function in print-lmp.c

The LMP parser in tcpdump before 4.9.3 has a buffer over-read in print-lmp.c:lmp_print_data_link_subobjs().

tcpdump: Buffer over-read in vrrp_print() function in print-vrrp.c

The VRRP parser in tcpdump before 4.9.3 has a buffer over-read in print-vrrp.c:vrrp_print() for VRRP version 2, a different vulnerability than CVE-2019-15167.

trim_whitespace in lexer.l in libConfuse v3.2.1 has an out-of-bounds read.

openstack-keystone: Information Exposure through /v3/OS-FEDERATION/projects

In the Federation component of OpenStack Keystone before 11.0.4, 12.0.0, and 13.0.0, an authenticated "GET /v3/OS-FEDERATION/projects" request may bypass intended access restrictions on listing projects. An authenticated user may discover projects they have no authority to access, leaking all projects in the deployment and their attributes. Only Keystone with the /v3/OS-FEDERATION endpoint enabled via policy.json is affected.

openjpeg2: Division-by-zero vulnerabilities in lib/openjp3d/pi.c

Division-by-zero vulnerabilities in the functions pi_next_pcrl, pi_next_cprl, and pi_next_rpcl in lib/openjp3d/pi.c in OpenJPEG through 2.3.0 allow remote attackers to cause a denial of service (application crash).

libavformat/movenc.c in FFmpeg 3.2 and 4.0.2 allows attackers to cause a denial of service (application crash caused by a divide-by-zero error) with a user crafted audio file when converting to the MOV audio format.

wireshark: HTTP2 dissector infinite loop (wnpa-sec-2018-41)

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 HTTP2 dissector could crash. This was addressed in epan/dissectors/packet-http2.c by verifying that header data was found before proceeding to header decompression.

wireshark: Bazaar dissector infinite loop (wnpa-sec-2018-40)

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 Bazaar protocol dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-bzr.c by properly handling items that are too long.

An issue was discovered in NeoMutt before 2018-07-16. newsrc.c does not properly restrict '/' characters that may have unsafe interaction with cache pathnames.
