Note from the SUSE Security Team

Only SUSE Linux Enterprise 9 is affected by this specific issue.

We evaluated the problem and find that the integer overflow will not cause allocations smaller than the passed content_length.

First, less than 0 values are checked already.

Second, as there is only a addition of 1, only INT_MAX is overflowing the integer addition.

As malloc gets at least an unsigned integer, and content_length is signed integer, due to the generated code by the compiler of signed integer to unsigned integer promotion all supported platforms get a positive value than INT_MAX if INT_MAX is passed in and will either fail malloc or allocate a INT_MAX+1 bytes of memory.

This means none of our platforms is affected by this issue.
