Detail
| A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) The following packages are affected: postfix The problem can be corrected by upgrading the affected package to version 2.1.3-1ubuntu17.1. In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Jean-Samuel Reynaud noticed a programming error in the IPv6 handling code of Postfix when /proc/net/if_inet6 is not available (which is the case in Ubuntu since Postfix runs in a chroot). If "permit_mx_backup" was enabled in the "smtpd_recipient_restrictions", Postfix turned into an open relay, i. e. erroneously permitted the delivery of arbitrary mail to any MX host which has an IPv6 address. |

| Title: | Buffer overflow in the X render (Xrender) extension in X.org X server 6.8.0 up to allows attackers to cause a denial of service (crash), as demonstrated by the (1) XRenderCompositeTriStrip and (2) XRenderCompositeTriFan requests in the rendertest from XCB xcb/xcb-demo, which leads to an incorrect memory allocation due to a typo in an expression that uses a "" instead of a "*" operator. NOTE: the subject line of the original announcement used an incorrect CVE number for this issue. | ||
| Description: | Postfix 2.1.3, when /proc/net/if_inet6 is not available and permit_mx_backup is enabled in smtpd_recipient_restrictions, allows remote attackers to bypass e-mail restrictions and perform mail relaying by sending mail to an IPv6 hostname. | ||
