RedHat: Low: gdb security update RHSA-2005:709-01
Summary
Summary
GDB, the GNU debugger, allows debugging of programs written in C, C++, and other languages by executing them in a controlled fashion, then printing their data. Several integer overflow bugs were found in gdb. If a user is tricked into processing a specially crafted executable file, it may allow the execution of arbitrary code as the user running gdb. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1704 to this issue. A bug was found in the way gdb loads .gdbinit files. When a user executes gdb, the local directory is searched for a .gdbinit file which is then loaded. It is possible for a local user to execute arbitrary commands as the victim running gdb by placing a malicious .gdbinit file in a location where gdb may be run. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1705 to this issue. This updated package also addresses the following issues: - - GDB on ia64 had previously implemented a bug fix to work-around a kernel problem when creating a core file via gcore. The bug fix caused a significant slow-down of gcore. - - GDB on ia64 issued an extraneous warning when gcore was used. - - GDB on ia64 could not backtrace over a sigaltstack. - - GDB on ia64 could not successfully do an info frame for a signal trampoline. - - GDB on AMD64 and Intel EM64T had problems attaching to a 32-bit process. - - GDB on AMD64 and Intel EM64T was not properly handling threaded watchpoints. - - GDB could not build with gcc4 when -Werror flag was set. - - GDB had problems printing inherited members of C++ classes. - - A few updates from mainline sources concerning Dwarf2 partial die in cache support, follow-fork support, interrupted syscall support, and DW_OP_piece read support. All users of gdb should upgrade to this updated package, which resolves these issues.
