Redhat : Security Vulnerabilities, CVEs, Published In November 2007

Heap-based buffer overflow in cygwin1.dll in Cygwin 1.5.7 and earlier allows context-dependent attackers to execute arbitrary code via a filename with a certain length, as demonstrated by a remote authenticated user who uses the SCP protocol to send a file to the Cygwin machine, and thereby causes scp.exe on this machine to execute, and then overwrite heap memory with characters from the filename. NOTE: it is also reported that a related issue might exist in 1.5.7 through 1.5.19.

buttonpressed.sh in scanbuttond 0.2.3 allows local users to overwrite arbitrary files via a symlink attack on the (1) scan.pnm and (2) scan.jpg temporary files.

Multiple integer overflows in Cairo before 1.4.12 might allow remote attackers to execute arbitrary code, as demonstrated using a crafted PNG image with large width and height values, which is not properly handled by the read_png function.

Memory leak in the Red Hat Content Accelerator kernel patch in Red Hat Enterprise Linux (RHEL) 4 and 5 allows local users to cause a denial of service (memory consumption) via a large number of open requests involving O_ATOMICLOOKUP.

Buffer overflow in the polymorphic opcode support in the Regular Expression Engine (regcomp.c) in Perl 5.8 allows context-dependent attackers to execute arbitrary code by switching from byte to Unicode (UTF) characters in a regular expression.

Certificate Server 7.2 in Red Hat Certificate System (RHCS) does not properly handle new revocations that occur while a Certificate Revocation List (CRL) is being generated, which might prevent certain revoked certificates from appearing on the CRL quickly and allow users with revoked certificates to bypass the intended CRL.

Algorithmic complexity vulnerability in the MCS translation daemon in mcstrans 0.2.3 allows local users to cause a denial of service (temporary daemon outage) via a large range of compartments in sensitivity labels.

The ricci daemon in Red Hat Conga 0.10.0 allows remote attackers to cause a denial of service (loss of new connections) by repeatedly sending data or attempting connections.
