In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task. En el kernel de Linux, en versiones anteriores a la 4.20.14, expand_downwards en mm/mmap.c carece de una comprobación para la dirección mínima de mmap, lo que facilita que los atacantes exploten desreferencias de puntero NULL en el kernel en plataformas que no son SMAP. Esto esto está relacionado con una comprobación de capacidades para la tarea equivocada. A flaw was found in mmap in the Linux kernel allowing the process to map a null page. • https://www.exploit-db.com/exploits/46502 https://www.exploit-db.com/exploits/47957 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0a1d52994d440e21def1c2174932410b4f2a98a1 http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00052.html http://packetstormsecurity.com/files/156053/Reliable-Datagram-Sockets-RDS-rds_atomic_free_op-Privilege-Escalation.html http://www.securityfocus.com/bid/107296 https&# • CWE-476: NULL Pointer Dereference •

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. En Wireshark, desde la versión 2.4.0 hasta la 2.4.12 y desde la 2.6.0 hasta la 2.6.6, el disector ASN.1 BER y relacionados podrían cerrarse inesperadamente. Esto se abordó en epan/dissectors/packet-ber.c, previniendo un desbordamiento de búfer asociado con dígitos excesivos en los valores de tiempo. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00027.html http://www.securityfocus.com/bid/107203 https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=15447 https://code.wireshark.org/review/gitweb?p=wireshark.git%3Ba=commit%3Bh=f8fbe9f934d65b2694fa74622e5eb2e1dc8cd20b https://lists.debian.org/debian-lts-announce/2019/03/msg00031.html https:/ • CWE-193: Off-by-one Error CWE-787: Out-of-bounds Write •

If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •

The UIProcess subsystem in WebKit, as used in WebKitGTK through 2.23.90 and WebKitGTK+ through 2.22.6 and other products, does not prevent the script dialog size from exceeding the web view size, which allows remote attackers to cause a denial of service (Buffer Overflow) or possibly have unspecified other impact, related to UIProcess/API/gtk/WebKitScriptDialogGtk.cpp, UIProcess/API/gtk/WebKitScriptDialogImpl.cpp, and UIProcess/API/gtk/WebKitWebViewGtk.cpp, as demonstrated by GNOME Web (aka Epiphany). El subsistema UIProcess en WebKit, tal y como se utiliza en WebKitGTK, hasta la versión 2.23.90, y WebKitGTK+, hasta la versión 2.22.6 y otros productos, no evita que el tamaño del diálogo del script sobrepase el tamaño de la vista web, lo que permite que los atacantes remotos provoquen una denegación de servicio (desbordamiento de búfer) o, posiblemente, otro tipo de impacto sin especificar. Esto está relacionado con UIProcess/API/gtk/WebKitScriptDialogGtk.cpp, UIProcess/API/gtk/WebKitScriptDialogImpl.cpp y UIProcess/API/gtk/WebKitWebViewGtk.cpp, tal y como queda demostrado por GNOME Web (también conocido como Epiphany). • https://www.exploit-db.com/exploits/46465 http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00005.html https://bugs.webkit.org/show_bug.cgi?id=184875 https://github.com/WebKit/webkit/commit/6f9b511a115311b13c06eb58038ddc2c78da5531 https://trac.webkit.org/changeset/241515/webkit https://usn.ubuntu.com/3948-1 https://www.inputzero.io/2019/02/fuzzing-webkit.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. A number of heap-based buffer over-read instances are present in mbstring regular expression functions when supplied with invalid multibyte data. These occur in ext/mbstring/oniguruma/regcomp.c, ext/mbstring/oniguruma/regexec.c, ext/mbstring/oniguruma/regparse.c, ext/mbstring/oniguruma/enc/unicode.c, and ext/mbstring/oniguruma/src/utf32_be.c when a multibyte regular expression pattern contains invalid multibyte sequences. Se ha descubierto un problema en PHP en versiones anteriores a la 5.6.40, versiones 7.x anteriores a la 7.1.26, versiones 7.2.x anteriores a la 7.2.14 y versiones 7.3.x anteriores a la 7.3.1. Existen instancias de sobrelectura de búfer basada en memoria dinámica (heap) en las funciones de expresión regular mbstring cuando se les proporcionan datos multibyte inválidos. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00083.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00104.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00044.html http://www.securityfocus.com/bid/107156 https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:3299 https://bugs.php.net/bug.php?id=77370 https://bugs. • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read •
