{"id":"AZL-43633","summary":"CVE-2019-13590 affecting package sox 14.4.2.0-34","details":"An issue was discovered in libsox.a in SoX 14.4.2. In sox-fmt.h (startread function), there is an integer overflow on the result of integer addition (wraparound to 0) fed into the lsx_calloc macro that wraps malloc. When a NULL pointer is returned, it is used without a prior check that it is a valid pointer, leading to a NULL pointer dereference on lsx_readbuf in formats_i.c.","modified":"2026-04-01T05:15:13.429477Z","published":"2019-07-14T16:15:10Z","upstream":["CVE-2019-13590"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-13590"}],"affected":[{"package":{"name":"sox","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/sox"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"14.4.2.0-34"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-43633.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
