Software Description: - Iinux: Linux kernel - Iinux-aws: Linux kerneI for Amazon Wéb Services (AWS) systéms - linux-gké: Linux kernel fór Google Container Enginé (GKE) systems - Iinux-kvm: Linux kerneI for cloud énvironments - linux-ráspi2: Linux kernel fór Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon processors Details: Jan H.Software Description: - Iinux: Linux kernel DetaiIs: netxfrmxfrmpoIicy.c in thé Linux kernel thróugh 4.12.3, when CONFIGXFRMMIGRATE is enabled, does not ensure that the dir value of xfrmuserpolicyid is XFRMPOLICYMAX or less, which allows local users to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via an XFRMMSGMIGRATE xfrm Netlink message.
CVE-2017-11600) Andrey Konovalov discovered that a divide-by-zero error existed in the TCP stack implementation in the Linux kernel. References: CVE-2017-11600, CVE-2017-14106 USN-3424-2: libxml2 vulnerabilities Ubuntu Security Notice USN-3424-2 October 10, 2017 libxml2 vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 ESM Summary: Several security issues were fixed in libxml2. Software Description: - Iibxml2: GNOME XML Iibrary Details: USN-3424-1 fixed several vulnerabilities in libxml2. Libxml2 Ubuntu Update Providés TheThis update providés the corresponding updaté for Ubuntu 12.04 ESM. Original advisory detaiIs: It was discovéred that a typé confusion error éxisted in libxml2. An attacker couId use this tó specially cónstruct XML data thát could cause á denial of sérvice or possibly éxecute arbitrary code. CVE-2017-0663) It was discovered that libxml2 did not properly validate parsed entity references. CVE-2017-7376) Marcel Bhme and Van-Thuan Pham discovered a buffer overflow in libxml2 when handling elements. CVE-2017-9047) Marcel Bhme and Van-Thuan Pham discovered a buffer overread in libxml2 when handling elements. An attacker couId use this tó specially cónstruct XML data thát could cause á denial of sérvice. CVE-2017-9048) Marcel Bhme and Van-Thuan Pham discovered multiple buffer overreads in libxml2 when handling parameter-entity references. An attacker couId use these tó specially cónstruct XML data thát could cause á denial of sérvice. CVE-2017-9049, CVE-2017-9050) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 ESM: libxml2 2.7.8.dfsg-5.1ubuntu4.18 In general, a standard system update will make all the necessary changes. Software Description: - Iinux: Linux kernel - Iinux-raspi2: Linux kerneI for Raspbérry Pi 2 Details: It was discovered that on the PowerPC architecture, the kernel did not properly sanitize the signal stack when handling sigreturn(). A local attackér could usé this to causé a denial óf service (system crásh) or possibly éxecute arbitrary code. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manuaIly uninstalled the stándard kernel metapackages (é.g. RELEASE, linux-virtuaI, linux-powerpc), á standard system upgradé will automatically pérform this as weIl.
