This update for krb5 fixes the following issues: - CVE-2026-107708: Denial of Service via malformed PAC in S4U2Proxy requests (bsc#1284816). - CVE-2026-107778: Denial of Service via crafted forwarded credentials (bsc#1284817).
This update for krb5 fixes the following issue - CVE-2026-11850: integer underflow in berval2tl_data() leads to heap out-of-bounds read (bsc#1268131).
This update for krb5 fixes the following issues: - CVE-2025-3576: weakness in the MD5 checksum design allows for spoofing of GSSAPI-protected messages that are using RC4-HMAC-MD5 (bsc#1241219). Krb5 as very old protocol supported quite a number of ciphers that are not longer up to current cryptographic standards. To avoid problems with those, SUSE has by default now disabled those alorithms. The following algorithms have been removed from valid krb5 enctypes: - des3-cbc-sha1 - arcfour-hmac-md5 To reenable those algorithms, you can use allow options in krb5.conf: [libdefaults] allow_des3 = true allow_rc4 = true to reenable them.
This update for krb5 fixes the following issues: - CVE-2025-24528: Fixed out-of-bounds write caused by overflow when calculating ulog block size can lead to process crash (bsc#1236619).
