Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
Multiple vulnerabilities have been reported in CVS, where one has an unknown impact and others which can be exploited by malicious people to cause a DoS (Denial of Service) and compromise a vulnerable system.

1) A boundary error in the CVS client during processing of version and author information can be exploited to cause a buffer overflow and execute arbitrary code by tricking a user into connecting to a malicious CVS server.

2) Some memory leaks and NULL pointer dereferences may be exploited to cause a DoS.

3) An unspecified error caused due to an arbitrary free has an unknown impact.

4) Some errors in the contributed Perl scripts can be exploited to execute arbitrary code via a malicious Perl library.

Successful exploitation requires that the user has commit access and that one of the contributed Perl scripts has been installed improperly.
