A code execution vulnerability exists in the WS-Addressing plugin functionality of Genivia gSOAP 2.8.107. A specially crafted SOAP request can lead to remote code execution. An attacker can send an HTTP request to trigger this vulnerability.

regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.

Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow.

Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection.
