A stack-buffer overflow vulnerability exists in all versions of sngrep since v1.4.1. The flaw is due to inadequate bounds checking when copying 'Content-Length' and 'Warning' headers into fixed-size buffers in the sipvalidatepacket and sipparseextraheaders functions within src/sip.c. This vulnerability allows remote attackers to execute arbitrary code or cause a denial of service (DoS) via crafted SIP messages.

A buffer overflow vulnerability exists in all versions of sngrep since v0.4.2, due to improper handling of 'Call-ID' and 'X-Call-ID' SIP headers. The functions sipgetcallid and sipgetxcallid in sip.c use the strncpy function to copy header contents into fixed-size buffers without checking the data length. This flaw allows remote attackers to execute arbitrary code or cause a denial of service (DoS) through specially crafted SIP messages.

A vulnerability was found in irontec klear-library chloe and classified as critical. Affected by this issue is the function prepareWhere of the file Controller/Rest/BaseController.php. The manipulation leads to sql injection. Upgrading to version marla is able to address this issue. The name of the patch is b25262de52fdaffde2a4434fc2a84408b304fbc5. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-221504.
