CVE-2007-3123: Buffer Overflow
First published: Thu Jun 07 2007(Updated: )
unrar.c in libclamav in ClamAV before 0.90.3 and 0.91 before 0.91rc1 allows remote attackers to cause a denial of service (core dump) via a crafted RAR file with a modified vm_codesize value, which triggers a heap-based buffer overflow.
