DO NOT REPLY [Bug 45084] New: A potential bug discovered by static
program analysis
https://issues.apache.org/bugzilla/show_bug.cgi?id=45084
Summary: A potential bug discovered by static program analysis
Product: Apache httpd-2
Version: 2.2.8
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P3
Component: Core
AssignedTo: bugs@httpd.apache.org
ReportedBy: rxc92@case.edu
File Name: /scrlib/apr/file_io/unix/seek.c
Function Nam: apr_file_trunc()
Correct Code:
99: apr_status_t apr_file_trunc(apr_file_t *fp, apr_off_t offset)
100: {
101: if (ftruncate(fp->filedes, offset) == -1) {
102: return errno;
103: }
104: return apr_file_seek(fp, APR_SET, &offset);
File Name: /src/rotatelogs.c
Function Nam: main()
Buggy Code:
263: apr_file_trunc(nLogFD, 0);
284: apr_file_trunc(nLogFD, 0);
File Name: /src/testbuckets.c
Function Nam: test_insertfile()
Buggy Code:
355: apr_file_trunc(f, 0);
419: apr_file_trunc(f, 0);
Description: A rule discovered by our static program analysis approach
indicates that an error occurs if apr_file_seek() outputs “!APR_SUCCESS”.
The function apr_file_trunc() returns the value outputted by apr_file_seek()
directly. Thus, it is inferred that an error occurs if apr_file_trunc() returns
“!APR_SUCCESS”. However, the outputs of apr_file_trunc() are not checked in
the above code.
