CVE-2010-3846

TITLE

CVS of rcs.c Is in apply_rcs_change Elevation of privilege vulnerability in functions

DESCRIPTION

Array index error in the apply_rcs_change function in rcs.c in CVS 1.11.23 allows local users to gain privileges via an RCS file containing crafted delta fragment changes that trigger a heap-based buffer overflow. Concurrent Versions System is an open source version control system. Enticing users to examine specially constructed files can trigger a heap-based buffer overflow. CVS is prone to a heap-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input before copying it to an insufficiently sized buffer. A local attacker can exploit this issue by storing a malicious RCS file in the CVS repository, and enticing an unsuspecting user to update their CVS repository tree with the file. Successful exploitation allows the attacker to execute arbitrary code with the privileges of the user running the vulnerable application. Failed attempts will result in denial-of-service conditions. ---------------------------------------------------------------------- Secure your corporate defenses and reduce complexity in handling vulnerability threats with the new Secunia Vulnerability Intelligence Manager (VIM) Beta.
