* libelf: Make sure string returned by elf_strptr is NUL terminated.Mark Wielaard2015-02-061-2/+21
| | | | | | | | | | The result of elf_strptr is often used directly to print or strcmp the string. If the section data was truncated or corrupted that could lead to invalid memory reads possibly crashing the application. https://bugzilla.redhat.com/show_bug.cgi?id=1170810#c24 Reported-by: Alexander Cherepanov <[email protected]> Signed-off-by: Mark Wielaard <[email protected]>
* libelf: elf_strptr should use datalist when data has been added to section.Mark Wielaard2015-02-061-6/+12
| | | | | | | | | | elf_strptr always used the rawdata when available. But when data has been added to the section it should find the correct buffer in the datalist. Adds a large testcase that checks various ways of adding and extracting strings from a section. Signed-off-by: Mark Wielaard <[email protected]>
* libelf: elf_strptr should fetch the shdr for the section if not yet known.Mark Wielaard2015-02-061-5/+7
| | | | | | | | | elf_strptr might be called before the shdrs are read in. In that case it needs to explicitly call __elf[32|64]_getshdr_rdlock to check the section type and size. The new strptr testcase triggers this corner case and crashes before the fix. Signed-off-by: Mark Wielaard <[email protected]>
