CVSS: 5.3EPSS: 0%CPEs: 2EXPL: 1CVE-2018-9251 – libxml2: infinite loop in xz_decomp function in xzlib.c
https://notcve.org/view.php?id=CVE-2018-9251
The xz_decomp function in xzlib.c in libxml2 2.9.8, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035. La función xz_decomp en xzlib.c en libxml2 2.9.8, si se emplea --with-lzma, permite que atacantes remotos provoquen una denegación de servicio (bucle infinito) mediante un archivo XML manipulado que desencadena LZMA_MEMLIMIT_ERROR, tal y como queda demostrado por xmllint. Esta vulnerabilidad es diferente de CVE-2015-8035. • https://bugzilla.gnome.org/show_bug.cgi?id=794914 https://lists.debian.org/debian-lts-announce/2018/09/msg00035.html https://access.redhat.com/security/cve/CVE-2018-9251 https://bugzilla.redhat.com/show_bug.cgi?id=1565318 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

Use after free in libxml2 before 2.9.5, as used in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. Uso de memoria previamente liberada en libxml2 en versiones anteriores a la 2.9.5, tal y como se emplea en Google Chrome en versiones anteriores a la 63.0.3239.84 y otros productos, permitía que un atacante remoto pudiese explotar una corrupción de memoria dinámica (heap) mediante una página HTML manipulada. A use-after-free flaw was found in the libxml2 library. An attacker could use this flaw to cause an application linked against libxml2 to crash when parsing a specially crafted XML file. • http://www.securitytracker.com/id/1040348 https://access.redhat.com/errata/RHSA-2017:3401 https://access.redhat.com/errata/RHSA-2018:0287 https://bugzilla.gnome.org/show_bug.cgi?id=783160 https://chromereleases.googleblog.com/2017/12/stable-channel-update-for-desktop.html https://crbug.com/727039 https://lists.debian.org/debian-lts-announce/2017/12/msg00014.html https://security.gentoo.org/glsa/201801-03 https://www.debian.org/security/2018/dsa-4086 https://access.redhat. • CWE-416: Use After Free •

An integer overflow in xmlmemory.c in libxml2 before 2.9.5, as used in Google Chrome prior to 62.0.3202.62 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted XML file. Un desbordamiento de enteros en xmlmemory.c en versiones anteriores a la 2.9.5 de libxml2, tal y como se emplea en Google Chrome, en versiones anteriores a la 62.0.3202.62 y en otros productos, permite que un atacante remoto explote la corrupción de la memoria dinámica (heap) mediante un archivo XML manipulado. A heap overflow flaw was found in the libxml2 library. An application compiled with libxml2 using the vulnerable debug-only function xmlMemoryStrdup could be used by an attacker to crash the application or execute arbitrary code with the permission of the user running the application. • http://bugzilla.gnome.org/show_bug.cgi?id=783026 http://www.securityfocus.com/bid/101482 https://access.redhat.com/errata/RHSA-2017:2997 https://chromereleases.googleblog.com/2017/10/stable-channel-update-for-desktop.html https://crbug.com/722079 https://git.gnome.org/browse/libxml2/commit/?id=897dffbae322b46b83f99a607d527058a72c51ed https://lists.debian.org/debian-lts-announce/2017/11/msg00034.html https://lists.debian.org/debian-lts-announce/2022/04/msg00004.html https://security.gentoo. • CWE-787: Out-of-bounds Write •
