{"id":"MGASA-2015-0466","summary":"Updated openssl packages fix security vulnerability","details":"If a client receives a ServerKeyExchange for an anonymous DH ciphersuite\nwith the value of p set to 0 then a seg fault can occur leading to a\npossible denial of service attack (CVE-2015-1794).\n\nLoic Jonas Etienne of Qnective AG discovered that the signature\nverification routines will crash with a NULL pointer dereference if\npresented with an ASN.1 signature using the RSA PSS algorithm and absent\nmask generation function parameter. A remote attacker can exploit this\nflaw to crash any certificate verification operation and mount a denial of\nservice attack (CVE-2015-3194).\n\nAdam Langley of Google/BoringSSL discovered that OpenSSL will leak memory\nwhen presented with a malformed X509_ATTRIBUTE structure (CVE-2015-3195).\n\nA race condition flaw in the handling of PSK identify hints was\ndiscovered, potentially leading to a double free of the identify hint data\n(CVE-2015-3196).\n","modified":"2026-02-01T19:15:31.081608Z","published":"2015-12-05T10:03:58Z","related":["CVE-2015-1794","CVE-2015-3194","CVE-2015-3195","CVE-2015-3196"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2015-0466.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=17292"},{"type":"REPORT","url":"http://openssl.org/news/secadv/20151203.txt"},{"type":"REPORT","url":"https://www.debian.org/security/2015/dsa-3413"}],"affected":[{"package":{"name":"openssl","ecosystem":"Mageia:5","purl":"pkg:rpm/mageia/openssl?arch=source&distro=mageia-5"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.2e-1.mga5"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2015-0466.json"}}],"schema_version":"1.7.3","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
