This flaw could cause an application that uses libxml2 to use an\nexcessive amount of memory.\n\nCVE-2015-7941\nlibxml2 does not properly stop parsing invalid input, which allows\ncontext-dependent attackers to cause a denial of service (out-of-bounds read\nand libxml2 crash) via crafted specially XML data.\n\nCVE-2015-7942\nThe xmlParseConditionalSections function in parser.c in libxml2\ndoes not properly skip intermediary entities when it stops parsing invalid\ninput, which allows context-dependent attackers to cause a denial of service\n(out-of-bounds read and crash) via crafted XML data.\n\nCVE-2015-7995\nThe xsltStylePreCompute function in preproc.c in libxslt 1.1.28 does not\ncheck whether the parent node is an element, which allows attackers to cause\na denial of service using a specially crafted XML document.\n\nCVE-2015-8035\nThe xz_decomp function in xzlib.c in libxml2 2.9.1 does not\nproperly detect compression errors, which allows context-dependent attackers\nto cause a denial of service (process hang) via crafted XML data.\n\nAnother vulnerability was discoverd in libxml2 that could cause parsing\nof unclosed comments to result in \"conditional jump or move depends on\nuninitialized value(s)\" and unsafe memory access. This issue does not have a\nCVE assigned yet. See related URLs for details.

This issue got addressed in libxml2 upstream and the\npatch has been backported to libxml2 in squeeze-lts.\n\n(2) #782985\n\nJun Kokatsu reported an out-of-bounds memory access in libxml2. By\nentering an unclosed html comment the libxml2 parser didn't stop\nparsing at the end of the buffer, causing random memory to be included\nin the parsed comment that was returned to the evoking application.\n\nIn the Shopify application (where this issue was originally\ndiscovered), this caused ruby objects from previous http requests to\nbe disclosed in the rendered page.\n\n(3) #783010\n\nMichal Zalewski reported another out-of-bound reads issue in libxml2\nthat did not cause any crashes but could be detected under ASAN and\nValgrind.\n\nNOTE: Tenable Network Security has extracted the preceding description\nblock directly from the DLA security advisory.

An unauthenticated, remote attacker can exploit this, via a saturation of partial HTTP requests, to cause a daemon outage. (CVE-2007-6750)\n\n - A cross-site scripting (XSS) vulnerability exists in jQuery when using location.hash to select elements. An unauthenticated, remote attacker can exploit this, via a specially crafted tag, to inject arbitrary script code or HTML into the user's browser session.\n (CVE-2011-4969)\n\n - A NULL pointer dereference flaw exists in file rsa_ameth.c due to improper handling of ASN.1 signatures that are missing the PSS parameter. A remote attacker can exploit this to cause the signature verification routine to crash, resulting in a denial of service condition. (CVE-2015-3194)\n\n - A flaw exists in the ASN1_TFLG_COMBINE implementation in file tasn_dec.c related to handling malformed X509_ATTRIBUTE structures. A remote attacker can exploit this to cause a memory leak by triggering a decoding failure in a PKCS#7 or CMS application, resulting in a denial of service. (CVE-2015-3195)\n\n - An out-of-bounds read error exists in cURL and libcurl within the smb_request_state() function due to improper bounds checking. An unauthenticated, remote attacker can exploit this, using a malicious SMB server and crafted length and offset values, to disclose sensitive memory information or to cause a denial of service condition. (CVE-2015-3237)\n\n - A flaw exists in libxslt in the xsltStylePreCompute() function within file preproc.c due to a failure to check if the parent node is an element. An unauthenticated, remote attacker can exploit this, via a specially crafted XML file, to cause a denial of service condition. (CVE-2015-7995)\n\n - An infinite loop condition exists in the xz_decomp() function within file xzlib.c when handling xz compressed XML content due to a failure to detect compression errors. An unauthenticated, remote attacker can exploit this, via specially crafted XML data, to cause a denial of service condition. (CVE-2015-8035)\n\n - A double-free error exists due to improper validation of user-supplied input when parsing malformed DSA private keys. A remote attacker can exploit this to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-0705)\n\n - An out-of-bounds read error exists in the fmtstr() function within file crypto/bio/b_print.c when printing very long strings due to a failure to properly calculate string lengths. An unauthenticated, remote attacker can exploit this, via a long string, to cause a denial of service condition, as demonstrated by a large amount of ASN.1 data. (CVE-2016-0799)\n\n - An unspecified flaw exists that allows a local attacker to impact the confidentiality and integrity of the system. No other details are available.
