Dear list, as discovered by Felix von Leitner (http://blog.fefe.de/?ts=b72905a8), Linux kernel patch 2.6.29.1 contains: --- a/fs/cifs/connect.c +++ b/fs/cifs/connect.c @@ -3667,7 +3667,7 @@ CIFSTCon(unsigned int xid, struct cifsSesInfo *ses, BCC(smb_buffer_response)) { kfree(tcon->nativeFileSystem); tcon->nativeFileSystem = - kzalloc(length + 2, GFP_KERNEL); + kzalloc(2*(length + 1), GFP_KERNEL); if (tcon->nativeFileSystem) cifs_strfromUCS_le( tcon->nativeFileSystem, fixing a remotely exploitable buffer overflow vulnerability in the CIFS protocol. Neither the Linux kernel team, the CIFS maintainers nor any of the commercial Linux distributors bothered to send out an advisory. I'm at loss for words other than "irresponsible, arrogant assholes".
