Dancer versions before 1.3400 for Perl pass unvalidated session ids from the session cookie to the session engine. read_session_id returns the cookie value as the session id without checking its characters, and Dancer hands it to the session engine to load the session. A remote attacker may…

HTTP::Session versions before 0.43 for Perl allow memcached command injection via unfiltered session ids in HTTP::Session::Store::Memcached. The session id from the client's cookie reaches memcached unchanged as the cache key. A CR and LF in the session id end the cache command early, and the…

JSON::XS versions from 3.04 before 4.05 for Perl write one byte past a heap buffer when appending a one-byte chunk in incr_parse. The incremental buffer grows to one and a half times the length it must hold, with no room reserved for the terminating NUL. For an empty buffer and a one-byte chunk…

JSON::XS versions before 4.05 for Perl leak the decoded part of a rejected long string in decode_str. A string is decoded through a fixed-size buffer (16 KiB in 4.04), and each time the buffer fills its contents move into a new scalar. Nothing frees that scalar when the string is then rejected…

JSON::XS versions from 4.0_00 before 4.05 for Perl corrupt the incremental buffer length by chopping past its end in incr_skip after a top-level number. The incremental parser scans any run of digits, signs, dots and exponent markers as one number, but the decoder stops at the end of a valid…

JSON::XS versions before 4.05 for Perl allow memory exhaustion by buffering incremental input past max_size after a NUL byte in incr_parse. The parser appends each chunk to its buffer and compares max_size with how far it has progressed, not with the buffer length. It treats a NUL byte as the end…
