{"id":"AZL-31838","summary":"CVE-2023-46724 affecting package squid 5.7-5","details":"Squid is a caching proxy for the Web. Due to an Improper Validation of Specified Index bug, Squid versions 3.3.0.1 through 5.9 and 6.0 prior to 6.4 compiled using `--with-openssl` are vulnerable to a Denial of Service attack against SSL Certificate validation. This problem allows a remote server to perform Denial of Service against Squid Proxy by initiating a TLS Handshake with a specially crafted SSL Certificate in a server certificate chain. This attack is limited to HTTPS and SSL-Bump. This bug is fixed in Squid version 6.4. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives. Those who you use a prepackaged version of Squid should refer to the package vendor for availability information on updated packages.","modified":"2026-04-01T05:10:48.659824Z","published":"2023-11-01T20:15:08Z","upstream":["CVE-2023-46724"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-46724"}],"affected":[{"package":{"name":"squid","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/squid"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.7-5"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-31838.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
