An issue was discovered in Xpdf 4.04. There is a crash in gfseek(_IO_FILE*, long, int) in goo/gfile.cc.

An issue was discovered in Bento4 1.6.0-639. A memory leak exists in AP4_StdcFileByteStream::Create(AP4_FileByteStream*, char const*, AP4_FileByteStream::Mode, AP4_ByteStream*&) in System/StdC/Ap4StdCFileByteStream.cpp.

An issue was discovered in Bento4 1.6.0-639. There ie excessive memory consumption in the function AP4_DataBuffer::ReallocateBuffer in Core/Ap4DataBuffer.cpp.

An issue was discovered in Bento4 through 1.6.0-639. A NULL pointer dereference occurs in AP4_File::ParseStream in Core/Ap4File.cpp, which is called from AP4_File::AP4_File.

### Impact In all the versions of NuProcess where it forks processes by using the JVM's Java_java_lang_UNIXProcess_forkAndExec method (1.2.0+), attackers can use NUL characters in their strings to perform command line injection. Java's ProcessBuilder isn't vulnerable because of a check in ProcessBuilder.start. NuProcess is missing that check. This vulnerability can only be exploited to inject command line arguments on Linux. - On macOS, any argument with a NUL character is truncated at that character. This means the malicious arguments are never seen by the started process. - On Windows, the entire command line is truncated at the first NUL character. This means the malicious arguments, and any intentional arguments provided after them, are never seen by the started process. ### Patches 2.0.5 ### Workarounds Users of the library can sanitize command strings to remove NUL characters prior to passing them to NuProcess for execution. ### References None.

In affected versions of Octopus Deploy it is possible to bypass rate limiting on login using null bytes.

A memory corruption vulnerability exists in the libpthread linuxthreads functionality of uClibC 0.9.33.2 and uClibC-ng 1.0.40. Thread allocation can lead to memory corruption. An attacker can create threads to trigger this vulnerability.

Ubuntu Security Notice 5647-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.
