CVE-2018-18493 – Mozilla: Buffer overflow in accelerated 2D canvas with Skia
https://notcve.org/view.php?id=CVE-2018-18493
A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. Puede ocurrir un desbordamiento de búfer en la librería SKIA durante los cálculos de un desplazamiento de búfer con acciones de hardware aceleradas de CANVAS 2D, debido al uso de cálculos de 32-bit en vez de 64-bit. Esto resulta en un cierre inesperado potencialmente explotable. • http://www.securityfocus.com/bid/106168 https://access.redhat.com/errata/RHSA-2018:3831 https://access.redhat.com/errata/RHSA-2018:3833 https://access.redhat.com/errata/RHSA-2019:0159 https://access.redhat.com/errata/RHSA-2019:0160 https://bugzilla.mozilla.org/show_bug.cgi?id=1504452 https://lists.debian.org/debian-lts-announce/2018/12/msg00002.html https://security.gentoo.org/glsa/201903-04 https://usn.ubuntu.com/3844-1 https://usn.ubuntu.com/3868-1 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2018-18498 – Mozilla: Integer overflow when calculating buffer sizes for images
https://notcve.org/view.php?id=CVE-2018-18498
A potential vulnerability leading to an integer overflow can occur during buffer size calculations for images when a raw value is used instead of the checked value. This leads to a possible out-of-bounds write. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. Puede ocurrir una vulnerabilidad potencial que conduce a un desbordamiento de enteros durante los cálculos de tamaño de búfer cuando se emplea un valor bruto en vez del valor comprobado. Esto conduce a una escritura fuera de límites. • http://www.securityfocus.com/bid/106168 https://access.redhat.com/errata/RHSA-2018:3831 https://access.redhat.com/errata/RHSA-2018:3833 https://access.redhat.com/errata/RHSA-2019:0159 https://access.redhat.com/errata/RHSA-2019:0160 https://bugzilla.mozilla.org/show_bug.cgi?id=1500011 https://lists.debian.org/debian-lts-announce/2018/12/msg00002.html https://security.gentoo.org/glsa/201903-04 https://usn.ubuntu.com/3844-1 https://usn.ubuntu.com/3868-1 https:/ • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
