CVSS: 8.8EPSS: 0%CPEs: 21EXPL: 0CVE-2020-10531 – ICU: Integer overflow in UnicodeString::doAppend()
https://notcve.org/view.php?id=CVE-2020-10531
An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp. Se detectó un problema en International Components for Unicode (ICU) para C/C++ versiones hasta 66.1. Se presenta un desbordamiento de enteros, conllevando a un desbordamiento de búfer en la región heap de la memoria, en la función UnicodeString::doAppend() en el archivo common/unistr.cpp. • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00004.html https://access.redhat.com/errata/RHSA-2020:0738 https://bugs.chromium.org/p/chromium/issues/detail?id=1044570 https://chromereleases.googleblog.com/2020/02/stable-channel-update-for-desktop_24.html https://chromium.googlesource.com/chromium/deps/icu/+/9f4020916eb1f28f3666f018fdcbe6c9a37f0e08 https://github.com/unicode-org/icu/commit/b7d08bc04a4296982fcef8b6b8a354a9e4e7afca https://github.com/unicode-org/icu/pull/971 https://lists.debian • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2017-17484
The ucnv_UTF8FromUTF8 function in ucnv_u8.cpp in International Components for Unicode (ICU) for C/C++ through 60.1 mishandles ucnv_convertEx calls for UTF-8 to UTF-8 conversion, which allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted string, as demonstrated by ZNC. La función ucnv_UTF8FromUTF8 en ucnv_u8.cpp en International Components for Unicode (ICU) para C/C++ hasta la versión 60.1 gestiona de manera incorrecta las llamadas ucnv_convertEx para la conversión UTF-8 a UTF-8. Esto permite que atacantes remotos provoquen una denegación de servicio (desbordamiento de búfer basado en pila y cierre inesperado de la aplicación) o, posiblemente, causen otro impacto sin especificar mediante una cadena manipulada, tal y como demuestra ZNC. • https://github.com/znc/znc/issues/1459 https://ssl.icu-project.org/trac/attachment/ticket/13490/poc.cpp https://ssl.icu-project.org/trac/changeset/40714 https://ssl.icu-project.org/trac/changeset/40715 https://ssl.icu-project.org/trac/ticket/13490 https://ssl.icu-project.org/trac/ticket/13510 https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Integer overflow in international date handling in International Components for Unicode (ICU) for C/C++ before 60.1, as used in V8 in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. Un desbordamiento de enteros en el manejo de fechas internacionales en International Components for Unicode (ICU) for C/C++ en versiones anteriores a la 60.1, tal y como se emplea en V8 en Google Chrome en versiones anteriores a la 63.0.3239.84 y otros productos, permitía que un atacante remoto realizase una lectura de memoria fuera de límites mediante una página HTML manipulada. • https://access.redhat.com/errata/RHSA-2017:3401 https://chromereleases.googleblog.com/2017/12/stable-channel-update-for-desktop.html https://crbug.com/774382 https://security.gentoo.org/glsa/201801-03 https://usn.ubuntu.com/3610-1 https://www.debian.org/security/2018/dsa-4150 https://access.redhat.com/security/cve/CVE-2017-15422 https://bugzilla.redhat.com/show_bug.cgi?id=1523136 • CWE-190: Integer Overflow or Wraparound •
