A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available for each\nvulnerability from the CVE link(s) in the References section.\n\nThe libarchive programming library can create and read several\ndifferent streaming archive formats, including GNU tar, cpio, and ISO\n9660 CD-ROM images. Libarchive is used notably in the bsdtar utility,\nscripting language bindings such as python-libarchive, and several\npopular desktop file managers.\n\nSecurity Fix(es) :\n\n* A flaw was found in the way libarchive handled hardlink archive\nentries of non-zero size. Combined with flaws in libarchive's file\nsystem sandboxing, this issue could cause an application using\nlibarchive to overwrite arbitrary files with arbitrary data from the\narchive. (CVE-2016-5418)\n\n* Multiple out-of-bounds write flaws were found in libarchive.\nSpecially crafted ZIP, 7ZIP, or RAR files could cause a heap overflow,\npotentially allowing code execution in the context of the application\nusing libarchive. (CVE-2016-1541, CVE-2016-4300, CVE-2016-4302)\n\n* Multiple out-of-bounds read flaws were found in libarchive.\nSpecially crafted LZA/LZH, AR, MTREE, ZIP, TAR, or RAR files could\ncause the application to read data out of bounds, potentially\ndisclosing a small amount of application memory, or causing an\napplication crash.

(CVE-2015-8916, CVE-2015-8917,\nCVE-2015-8922)\n\n* Multiple infinite loop / resource exhaustion flaws were found in\nlibarchive.

Attempting to create an\nISO9660 volume with 2 GB or 4 GB file names could cause the\napplication to attempt to allocate 20 GB of memory.

(CVE-2015-8916, CVE-2015-8917, CVE-2015-8922)\n\n* Multiple infinite loop / resource exhaustion flaws were found in libarchive. Specially crafted GZIP or ISO files could cause the application to consume an excessive amount of resources, eventually leading to a crash on memory exhaustion. (CVE-2016-7166, CVE-2015-8930)\n\n* A denial of service vulnerability was found in libarchive. A specially crafted CPIO archive containing a symbolic link to a large target path could cause memory allocation to fail, causing an application using libarchive that attempted to view or extract such archive to crash.

Libarchive is used notably in the bsdtar utility, scripting language bindings such as python-libarchive, and several popular desktop file managers.\n\nSecurity Fix(es):\n\n* A flaw was found in the way libarchive handled hardlink archive entries of non-zero size. Combined with flaws in libarchive's file system sandboxing, this issue could cause an application using libarchive to overwrite arbitrary files with arbitrary data from the archive. (CVE-2016-5418)\n\n* Multiple out-of-bounds write flaws were found in libarchive. Specially crafted ZIP, 7ZIP, or RAR files could cause a heap overflow, potentially allowing code execution in the context of the application using libarchive. (CVE-2016-1541, CVE-2016-4300, CVE-2016-4302)\n\n* Multiple out-of-bounds read flaws were found in libarchive. Specially crafted LZA/LZH, AR, MTREE, ZIP, TAR, or RAR files could cause the application to read data out of bounds, potentially disclosing a small amount of application memory, or causing an application crash. (CVE-2015-8919, CVE-2015-8920, CVE-2015-8921, CVE-2015-8923, CVE-2015-8924, CVE-2015-8925, CVE-2015-8926, CVE-2015-8928, CVE-2015-8934)\n\n* Multiple NULL pointer dereference flaws were found in libarchive. Specially crafted RAR, CAB, or 7ZIP files could cause an application using libarchive to crash. (CVE-2015-8916, CVE-2015-8917, CVE-2015-8922)\n\n* Multiple infinite loop / resource exhaustion flaws were found in libarchive. Specially crafted GZIP or ISO files could cause the application to consume an excessive amount of resources, eventually leading to a crash on memory exhaustion. (CVE-2016-7166, CVE-2015-8930)\n\n* A denial of service vulnerability was found in libarchive. A specially crafted CPIO archive containing a symbolic link to a large target path could cause memory allocation to fail, causing an application using libarchive that attempted to view or extract such archive to crash. (CVE-2016-4809)\n\n* An integer overflow flaw, leading to a buffer overflow, was found in libarchive's construction of ISO9660 volumes. Attempting to create an ISO9660 volume with 2 GB or 4 GB file names could cause the application to attempt to allocate 20 GB of memory. If this were to succeed, it could lead to an out of bounds write on the heap and potential code execution. (CVE-2016-6250)\n\n* Multiple instances of undefined behavior due to arithmetic overflow were found in libarchive. Specially crafted MTREE archives, Compress streams, or ISO9660 volumes could potentially cause the application to fail to read the archive, or to crash.
