libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.

libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.

libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller.

A certain Cisco JAR file, as distributed in Cache Cleaner in Cisco Secure Desktop (CSD), allows remote attackers to execute arbitrary commands via a crafted web site, aka Bug ID CSCup83001.

The WebLaunch feature in Cisco Secure Desktop before 3.6.6020 does not properly validate binaries that are received by the downloader process, which allows remote attackers to execute arbitrary code via vectors involving (1) ActiveX or (2) Java components, aka Bug IDs CSCtz76128 and CSCtz78204.

The HostScan downloader implementation in Cisco AnyConnect Secure Mobility Client 3.x before 3.0 MR8 and Cisco Secure Desktop before 3.6.6020 does not compare the timestamp of offered software to the timestamp of installed software, which allows remote attackers to force a version downgrade by using (1) ActiveX or (2) Java components to offer signed code that corresponds to an older software release, aka Bug ID CSCtx74235.

The Web Install ActiveX control (CSDWebInstaller) in Cisco Secure Desktop (CSD) before 3.5.841 does not properly verify the signatures of downloaded programs, which allows remote attackers to force the download and execution of arbitrary files via a crafted web page, aka Bug ID CSCta25876.

Sun Secure Global Desktop (SSGD, aka Tarantella) before 4.3 allows remote attackers to obtain sensitive information, including hostnames, versions, and settings details, via unspecified vectors, possibly involving (1) taarchives.cgi, (2) ttaAuthentication.jsp, (3) ttalicense.cgi, (4) ttawlogin.cgi, (5) ttawebtop.cgi, (6) ttaabout.cgi, or (7) test-cgi. NOTE: This information is based upon a vague initial disclosure. Details will be updated as they become available.

Multiple cross-site scripting (XSS) vulnerabilities in Sun Secure Global Desktop (SSGD, aka Tarantella) before 4.20.983 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, possibly involving (1) taarchives.cgi, (2) ttaAuthentication.jsp, (3) ttalicense.cgi, (4) ttawlogin.cgi, (5) ttawebtop.cgi, (6) ttaabout.cgi, or (7) test-cgi. NOTE: This information is based upon a vague initial disclosure. Details will be updated as they become available.

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (crash) via a crafted FlateDecode stream that triggers a null dereference.
