Ein Angreifer kann mehrere Schwachstellen in Dell Data Protection Advisor ausnutzen, um beliebigen Code auszuführen, einen Denial-of-Service-Zustand zu erzeugen, Sicherheitsmaßnahmen zu umgehen und nicht näher spezifizierte Angriffe zu starten.

The curl tool's "globbing" feature allows a user to specify a numerical range through which curl iterates. It is typically specified as `[1-5]`, specifying the first and the last numbers in the range. Or with `[a-z]`, using letters. 1. The curl code for parsing the second *unsigned* number did not check for a leading minus character, which allowed a user to specify `[1--1]` with no complaints and have the latter `-1` number get turned into the largest unsigned long value the system can handle. This would ultimately cause curl to write outside the dedicated heap allocated buffer after no less than 100,000 iterations, since it would have room for 5 digits but not 6. 2. When the range is specified with letters, and the ending letter is left out `[L-]`, the code would still advance its read pointer 5 bytes even if the string was 4 bytes and end up reading outside the given buffer. This flaw exists only in the curl tool, not in the libcurl library.
