An attacker could use\nthis to craft a malicious document that, when opened, could cause a\ndenial of service (application crash) or possible execute arbitrary\ncode. (CVE-2017-5029)\n\nNicolas Gregoire discovered that Libxslt mishandled namespace\nnodes. An attacker could use this to craft a malicious document that,\nwhen opened, could cause a denial of service (application crash)\nor possibly execute arbtrary code. This issue only affected Ubuntu\n16.04 LTS, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS. (CVE-2016-1683)\n\nSebastian Apelt discovered that a use-after-error existed in the\nxsltDocumentFunctionLoadDocument() function in Libxslt. An attacker\ncould use this to craft a malicious document that, when opened,\ncould cause a denial of service (application crash) or possibly\nexecute arbitrary code.

(CVE-2016-1841)\n\nIt was discovered that a type confusion error existed in the\nxsltStylePreCompute() function in Libxslt. An attacker could use this\nto craft a malicious XML file that, when opened, caused a denial of\nservice (application crash). This issue only affected Ubuntu 14.04\nLTS and Ubuntu 12.04 LTS.

This issue only affected Ubuntu 16.04 LTS,\nUbuntu 14.04 LTS, and Ubuntu 12.04 LTS. (CVE-2016-1684)\n\nIt was discovered that the xsltFormatNumberConversion() function\nin Libxslt did not properly handle empty decimal separators. An\nattacker could use this to craft a malicious document that, when\nopened, could cause a denial of service (application crash). This\nissue only affected Ubuntu 16.10, Ubuntu 16.04 LTS, Ubuntu 14.04 LTS,\nand Ubuntu 12.04 LTS.
