A flaw was found in the RPM Package Manager (RPM). A local user could be affected by a heap buffer overflow vulnerability when processing a specially crafted NDB database file. This issue arises from an error in how RPM handles certain calculations during file parsing, leading to an incorrect memory allocation. An attacker could leverage this to cause a denial of service, making the system unavailable.

CVE-2026-712617.8 HIG—
———dr_libs dr_wav.h (all versions through current master) contains an integer overflow in W64 CUE chunk metadata parsing. In drwav__metadata_process_chunk(), a stage-1 capacity estimate truncates the 64-bit W64 chunk sizeInBytes to size_t before dividing by DRWAV_CUE_POINT_BYTES; on 32-bit builds this truncation causes the pre-allocated extra metadata capacity to be computed incorrectly. The subsequent read in drwav__read_cue_to_metadata_obj() computes the actual cue point count and allocation size using the full-precision, attacker-controlled cuePointCount field without cross-checking it against the stage-1 capacity estimate, and the only bounds enforcement on the resulting memory region (drwav__metadata_get_memory()) is a DRWAV_ASSERT, which compiles to a no-op under -DNDEBUG (the default for release builds). A crafted W64 WAV file can therefore cause a heap buffer overflow in any 32-bit application parsing untrusted WAV metadata.11hCVE-2026-451037.5 HIG—
——0OpenSIPS is a Session Initiation Protocol (SIP) server implementation. In versions prior to 3.6.6 and 4.0.0-rc1, the TCP message framing layer parses the Content-Length header using unsigned int arithmetic with no overflow check. When an attacker sends a Content-Length value that overflows unsigned int (e.g., 4294967296), the framing layer computes a wrapped-around value (e.g., 0) and splits the TCP stream at the wrong boundary, causing the body of the first SIP message to be processed as a separate message and enabling SIP message smuggling. Because Content-Length is parsed in the transport layer before authentication, an unauthenticated, network-based attacker can smuggle arbitrary SIP messages over any TCP-based transport (proto_tcp, proto_tls, proto_ws, proto_wss) on any instance with TCP enabled, with no routing-script preconditions. This allows smuggled messages to bypass front-end SBC/proxy security policies, inherit the connection's authentication context, and evade rate limiting. This issue has been fixed in versions 3.6.6 and 4.0.0-rc1.8hCVE-2026-213667.8 HIG—
