CVSS: 7.5EPSS: 0%CPEs: 12EXPL: 0CVE-2023-29089 – Shannon Baseband Negative-Size Memcpy / Out-Of-Bounds Read
https://notcve.org/view.php?id=CVE-2023-29089
An issue was discovered in Samsung Exynos Mobile Processor, Automotive Processor and Modem for Exynos Modem 5123, Exynos Modem 5300, Exynos 980, Exynos 1080, Exynos 9110, and Exynos Auto T5123. Memory corruption can occur due to insufficient parameter validation while decoding SIP multipart messages. There is a negative-size memcpy (heap overflow) when decoding the body of SIP multipart messages. According to debug strings in the modem image, this functionality is implemented in IMSPL_SipFragDecode. • http://packetstormsecurity.com/files/172292/Shannon-Baseband-Negative-Size-Memcpy-Out-Of-Bounds-Read.html https://semiconductor.samsung.com/support/quality-support/product-security-updates • CWE-125: Out-of-bounds Read •
