- More information:
Fernando Muñoz discovered a security issue on the HTML syntax checker and reformatter tidy. Tidy did not properly process specific character sequences, and a remote attacker could exploit this flaw to cause a DoS, or probably, execute arbitrary code. Two different CVEs were assigned to this issue.
Malformed html documents could lead to a heap-buffer-overflow.
Malformed html documents could lead to allocate 4Gb of memory.
For the Squeeze distribution, this issue has been fixed in the 20091223cvs-1+deb6u1 version of tidy.
We recommend that you upgrade your tidy packages.
