Debian alert: New Heimdal packages fix remote command execution

  • Mailing list (Posted by dave on Oct 17, 2002 6:06 AM EDT)
  • Story Type: Security; Groups: Debian
The SuSE Security Team has reviewed critical parts of the Heimdal package such as the kadmind and kdc server. While doing so several potential buffer overflows and other bugs have been uncovered and fixed. Remote attackers can probably gain remote root access on systems without fixes. Since these services usually run on authentication servers these bugs are considered very serious.

The attacker is able to cause arbitrary code to be run with the privileges of the victim.

Debian alert: New syslog-ng packages fix buffer overflow

  • Mailing list (Posted by dave on Oct 15, 2002 5:36 AM EDT)
  • Story Type: Security; Groups: Debian
Péter Höltzl discovered a problem in the way syslog-ng handles macro expansion. When a macro is expanded a static length buffer is used accompanied by a counter. However, when constant chharacters are appended, the counter is not updated properly, leading to incorrect boundary checking. An attacker may be able to use specially crafted log messages inserted via UDP which overflows the buffer.

Updated packages for analog are available which fix a cross-site scripting problem and a denial of service problem.

Mandrake alert: kdelibs update

A vulnerability was discovered in Konqueror's cross site scripting protection, in that it fails to initialize the domains on sub-(i)frames correctly. Because of this, javascript may access any foreign subframe which is defined in the HTML source, which can be used to steal cookies from the client and allow other cross-site scripting attacks. This also affects other KDE software that uses the KHTML rendering engine. This is fixed in KDE 3.0.3a, and the KDE team provided a patch for KDE 2.2.2. This patch has been applied to the following packages. After upgrading kdelibs, you must restart KDE in order for the fix to work.

Debian alert: New bugzilla packages fix privilege escalation

  • Mailing list (Posted by dave on Oct 9, 2002 6:35 AM EDT)
  • Story Type: Security; Groups: Debian
The developers of Bugzilla, a web-based bug tracking system, discovered a problem in the handling of more than 47 groups. When a new product is added to an installation with 47 groups or more and "usebuggroups" is enabled, the new group will be assigned a groupset bit using Perl math that is not exact beyond 2^48. This results in the new group being defined with a "bit" that has several bits set. As users are given access to the new group, those users will also gain access to spurious lower group privileges. Also, group bits were not always reused when groups were deleted.
