1 CVE-2008-1685 119 Overflow 2008-04-06 2012-10-29
6.8
User Remote Medium Not required Partial Partial Partial
** DISPUTED ** gcc 4.2.0 through 4.3.0 in GNU Compiler Collection, when casts are not used, considers the sum of a pointer and an int to be greater than or equal to the pointer, which might lead to removal of length testing code that was intended as a protection mechanism against integer overflow and buffer overflow attacks, and provide no diagnostic message about this removal. NOTE: the vendor has determined that this compiler behavior is correct according to section 6.5.6 of the C99 standard (aka ISO/IEC 9899:1999).
2 CVE-2008-1367 399 Mem. Corr. 2008-03-17 2010-08-21
7.5
User Remote Low Not required Partial Partial Partial
gcc 4.3.x does not generate a cld instruction while compiling functions used for string manipulation such as memcpy and memmove on x86 and i386, which can prevent the direction flag (DF) from being reset in violation of ABI conventions and cause data to be copied in the wrong direction during signal handling in the Linux kernel, which might allow context-dependent attackers to trigger memory corruption. NOTE: this issue was originally reported for CPU consumption in SBCL.
3 CVE-2006-1902 119 Overflow 2006-04-20 2011-02-10
2.1
None Local Low Not required None Partial None
fold_binary in fold-const.c in GNU Compiler Collection (gcc) 4.1 improperly handles pointer overflow when folding a certain expr comparison to a corresponding offset comparison in cases other than EQ_EXPR and NE_EXPR, which might introduce buffer overflow vulnerabilities into applications that could be exploited by context-dependent attackers.NOTE: the vendor states that the essence of the issue is "not correctly interpreting an offset to a pointer as a signed value."
4 CVE-2000-1219 Overflow 2000-11-01 2008-09-05
7.5
None Remote Low Not required Partial Partial Partial
The -ftrapv compiler option in gcc and g++ 3.3.3 and earlier does not handle all types of integer overflows, which may leave applications vulnerable to vulnerabilities related to overflows.
