Integer overflow in the JPEGImageReader implementation in the ImageI/O component in Sun Java SE in JDK and JRE 5.0 before Update 22, JDK and JRE 6 before Update 17, and SDK and JRE 1.4.x before 1.4.2_24 allows remote attackers to execute arbitrary code via large subsample dimensions in a JPEG file that triggers a heap-based buffer overflow, aka Bug Id 6874643.

The MessageDigest.isEqual function in Java Runtime Environment (JRE) in Sun Java SE in JDK and JRE 5.0 before Update 22, JDK and JRE 6 before Update 17, SDK and JRE 1.3.x before 1.3.1_27, and SDK and JRE 1.4.x before 1.4.2_24 allows remote attackers to spoof HMAC-based digital signatures, and possibly bypass authentication, via unspecified vectors related to "timing attack vulnerabilities," aka Bug Id 6863503.

Unspecified vulnerability in Sun Java SE in JDK and JRE 5.0 before Update 22, JDK and JRE 6 before Update 17, SDK and JRE 1.3.x before 1.3.1_27, and SDK and JRE 1.4.x before 1.4.2_24 allows remote attackers to cause a denial of service (memory consumption) via crafted HTTP headers, which are not properly parsed by the ASN.1 DER input stream parser, aka Bug Id 6864911.

Unspecified vulnerability in the LDAP implementation in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 17 and earlier; 6 Update 12 and earlier; SDK and JRE 1.3.1_24 and earlier; and 1.4.2_19 and earlier allows remote LDAP servers to execute arbitrary code via unknown vectors related to serialized data.

LdapCtx in the LDAP service in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 17 and earlier; 6 Update 12 and earlier; SDK and JRE 1.3.1_24 and earlier; and 1.4.2_19 and earlier does not close the connection when initialization fails, which allows remote attackers to cause a denial of service (LDAP service hang).

Buffer overflow in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 17 and earlier; 6 Update 12 and earlier; 1.4.2_19 and earlier; and 1.3.1_24 and earlier allows remote attackers to access files or execute arbitrary code via a crafted GIF image, aka CR 6804998.

Unspecified vulnerability in Java Runtime Environment (JRE) for Sun JDK and JRE 5.0 Update 16 and earlier; SDK and JRE 1.4.2_18 and earlier; and SDK and JRE 1.3.1_23 or earlier allows untrusted applets and applications to read arbitrary memory via a crafted ZIP file.

Unspecified vulnerability in Java Runtime Environment (JRE) with Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; SDK and JRE 1.4.2_18 and earlier; and SDK and JRE 1.3.1_23 and earlier allows code that is loaded from a local filesystem to read arbitrary files and make unauthorized connections to localhost via unknown vectors.

Buffer overflow in Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; SDK and JRE 1.4.2_18 and earlier; and SDK and JRE 1.3.1_23 and earlier might allow remote attackers to execute arbitrary code, related to a ConvolveOp operation in the Java AWT library.

Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; SDK and JRE 1.4.2_18 and earlier; and SDK and JRE 1.3.1_23 and earlier creates temporary files with predictable file names, which allows attackers to write malicious JAR files via unknown vectors.
