parse_content_length(): Fix out-of-bounds read edge-case (OSS-Fuzz)
This patch fixes a possible off-by-one read overflow while parsing a bad
Content-Length header. The error was mostly harmless, as the supplied
buffer is typically much larger and is stored in PKG memory.
Severity: Low
Fixes OSS-Fuzz#53199
(cherry picked from commit a008e7c2385bcd83de2f9ab155ed8a9452bf3c5c)
