DEBIAN-CVE-2010-1324
MIT Kerberos 5 aka krb5 1.7.x and 1.8.x through 1.8.3 does not properly determine the acceptability of checksums, which might allow remote attackers to forge GSS tokens, gain privileges, or have unspecified other impact via 1 an unkeyed checksum, 2 an unkeyed PAC checksum, or 3 a KrbFastArmoredRe...
Design/Logic Flaw
MIT Kerberos 5 aka krb5 1.8.x through 1.8.3 does not reject RC4 key-derivation checksums, which might allow remote authenticated users to forge a 1 AD-SIGNEDPATH or 2 AD-KDC-ISSUED signature, and possibly gain privileges, by leveraging the small key space that results from certain one-byte...
