Security vulnerability affects the expat package. This issue is resolved in later releases. See references for vulnerability details.

In Expat (aka libexpat) before 2.4.5, there is an integer overflow in copyString.

libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse, if one of them matches the setup. Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*, which could lead to libcurl reusing wrong connections. File paths are, or can be, case sensitive on many systems but not all, and can even vary depending on used file systems. The comparison also didn't include the 'issuer cert' which a transfer can set to qualify how to verify the server certificate. curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl. This rarely used option is used to send variable=content pairs to TELNET servers. Due to flaw in the option parser for sending `NEW_ENV` variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server. Therefore potentially revealing sensitive internal information to the server using a clear-text network protocol. This could happen because curl did not call and use sscanf() correctly when parsing the string provided by the application. In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory). In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for m_groupSize. addBinding in xmlparse.c in Exp…

In Expat (aka libexpat) before 2.4.5, there is an integer overflow in copyString.

Several vulnerabilities have been discovered in the Expat XML parser library (aka libexpat).This open-source component is widely used in a lot of products worldwide.A remote, anonymous attacker could use an integer overflow to execute arbitrary program code when loading specially crafted XML files. Profinet SDK is using XML parser library Expat as reference solution for loading the XML based Profinet network configuration files (IPPNIO or TIC).
